List the many diagnostic and therapeutic procedures in medical imaging. Differentiate the many career opportunities and various specialties in radiography. Define terms related to radiologic technology. Discovery of X-Rays November 8, 1895, Wilhelm Conrad Roentgen discovered X-ray accidentally while working in his lab. It was then called X-Ray or Roentgen ray. December 28, 1895, the first report was titled “On a New Kind of Rays” Discovery of X-Rays First X-Ray Tube: “Crooke’s Tube” Discovery of X-Rays X-ray was discovered before Roentgen by other scientists, but all failed to grasp its significance. Roentgen was the first to grasp the significance of Roentgen’s Laboratory the penetrating ability of Barium platinocyanide X-Ray. History of Radiologic Technology In 1901 Roentgen received the First Nobel Prize in Physics for his discovery. On February 10, 1923, Roentgen died in Munich.

The image remains invisible until processed in a darkroom. The processor contains the wet chemistry (developer agents, fixer agents and dryer). The image is viewed using a lighted view box and stored in tangible files. Conventional Radiography Note: In conventional radiography, the image is acquired on film in a light- tight cassette. It is then immersed in a wet chemistry for development. The final image is seen as a hard copy (radiograph) that is placed on a view box for interpretation. The final processed image is called a: Radiograph Computed Radiography (CR) Conventional Radiographic projection radiography in which the latent image (unseen image) is produced in digital format using computer technology. The image is acquired in a phosphor material plate inside a closed cassette. It is then inserted into an image reader device where it is scanned by a laser beam and the final image appears on a computer monitor. Digital Radiography Medical Imaging Terminology & References Anatomic Position –The person is standing erect with palms facing forward. Everything that faces forward is anterior and everything that faces backward is posterior Medical Imaging Terminology & References Projection The path of radiation as it passes through the patient to the IR. When the CR enters the front (anterior) surface of the body and exits the back (posterior), an AnteroPosterioor (AP) projection is obtained. Projections Posteroanterior (PA) – Designates the beam entering the posterior (back) surface of the body and exiting the anterior (front) surface of the body. Posteroanterior (PA) Projection Projections Lateral projection: A projection in which the CR enters one side of the body or body part and traverses and exits on the opposite side. Projections Oblique Projection: The CR enters the body or body part from a side angle. An oblique projection does not place the body or body part in an AP, PA or a lateral, but somewhere between those positions. Positioning Aids Sponges, sandbags, tapes, restraint are used to control voluntary and involuntary motion. These tools must be radiolucent otherwise will cast a shadow on the radiograph. Voluntary vs. Involuntary Motion Nervousness Heart pulsation Discomfort Chill Excitability Peristalsis Mental illness Tremor Fear Spasm Age Pain Breathing Radiolucent Items which will not cast a shadow on the radiograph. These items are easily penetrated by x-ray. Example: Positioning sponges Radiopaque Metallic or non- metallic items which will cast a shadow on the radiograph. These items are not easily penetrated by x-ray. Example: jewelry, barium, positioning sand bags, prosthesis etc. Bedside or Portable Unit Mobile units used to radiograph patients who are unable to be brought to the radiology department X-Ray Films Film Screen film mainly sensitive to blue light emitted by intensifying screens. Screen=white part of cassette Also sensitive to x- rays. Cassette with Screens Half inch thick metal framed film holder with a pair of intensifying screens mounted on the inside of the front and back hinged panels. Used with screen film. A thin sheet of cardboard or plastic covered on one side with a fluorescent material that emits blue or green light when exposed to x-rays. Used in cassette film holders. View Boxes/Monitors Radiographic Illuminators aka: ”View boxes” Used for mounting radiographs for critique and interpretation. Now replaced with high resolution monitors Calipers Calipers measuring device calibrated in centimeters and inches. Used to measure the part or region to be radiographed. Lead Letters/Numbers Lead Letters and Numerals Placed on image receptor before exposure to identify left or right side of part or region and to identify the patient and technologist. Grids & Bucky Grid/Stationary Grid/Moving Grid A wafer thin grid of alternate lead and plastic strips placed between the object to be x-rayed and the x-ray film. Removes unwanted scattered radiation. Bucky Tray Tray beneath x-ray table top for x-ray cassette. Above tray is moving grid placed between table top and tray. The X-Ray Tube A glass vacuumed tube suspended from the ceiling over the radiographic table. X- rays are produced in the tube and released through the port or window on the underside of tube. Shields Leaded Rubber Apron & Gloves Used for protection from x-rays. Gonadal Shields Lead impregnated material that is worn over gonad area for protection from x-rays. May use lead rubber mask and lead gloves on males, lead apron on females if no appropriate shield is available. INTRODUCTION TO RADIOLOGIC TECHNOLOGY RAD 1124–Week 4 Dr. Lillian Amann, DHSc, RT (R) Learning Outcomes Describe the changes to the radiology department since the 1960s. Identify & discuss the organizational structure of a radiology department. Describe the role of a radiology administrator. Explain how radiology is thought of as a business. Identify high volume areas within a radiology department. Review the basics of identifying Medical Terminology. Historical Perspectives Before the 1960s, hospital radiology departments were very simple in structure and function. The organization tables from one hospital to the next carried great similarities with just one modality. Evolution of Radiology Most dynamic period of growth: 1960s Responsible: Computer application Outcome: Development ultrasound, CT, MRI, vascular/interventional technology etc. Evolution of Radiology These new applications gave rise to a change in the reference “Radiology Department” to: “Diagnostic Imaging Department”. Before the 1960s Radiology Department X-Ray Before the 1960s Administrator Chief Tech X-Ray Techs Support Staff From the 1960s on Director/Manager Chief Technologist Radiologic Technologists Support Staff Modern Medical Imaging Departments Administrative Director (1) Assistant Administ. Administrative Secretary Director (1) (1) And Assistant Technical. Manager (1) Supervisors (4) Technologists (Many) Support Staff (Many) Modern Medical Imaging Departments NM PET US CT General MRI Diagnostic CT Imaging Bone Mammo Special/ Mammo Dens. Interventional Equipment Location Another change to consider is the placement of radiology equipment and services in different areas of the hospital. Such equipment may be found today in an endoscopy suite, interventional vascular suite in surgery, in the ER, the outpatient pre-admission testing department etc. Modern Medical Imaging Departments One Consistency There is one consistency, however, found between the old and the new department. High volume area within a radiology department remains: General In-patient and General Out-patient. Modern Medical Imaging Departments The organizational structure of the modern radiology department is very complex. Because of the constant emergence of new technology, staffing and management role continues to experiment with new titles, new responsibilities and additional training accordingly. Administrative Director Responsibilities: The role of the Administrative director of radiology is to oversee the operation of the whole department including departmental planning and organization, rad. safety, Quality management, budgeting, staffing of technical and clerical services, and equipment maintenance. Administrative Director Additional Responsibilities: equipment selection, personnel evaluations, hiring and firing, policy and procedures, and department productivity. This position usually reports to the department’s medical director. The Business of Radiology The radiology department of today is thought of as a business. Through health care reform, managed care brought about the following challenges: Cost containment Competition Cost Containment Radiology is forced to position itself as a revenue-making department with an eye on set benchmark which must be met per month or quarter. This is done through active financial analysis. This challenges radiology managers to maintain tighter control over staffing and allocation of supplies as well as other resources. Competition Due to shorter hospital LOS, radiology must compete with other departments from other hospitals and private centers for business. This is done by offering: A. Shorter turnaround of radiology reports (within 6 hours of the procedure) B. Better quality images (consistent) C. Faster services to the patients: (less than 15 min wait) Competition D. Greater patient satisfaction E. Broader range of services to the patients and referring physicians F. State-of-the-art equipment G. Employee satisfaction (incentives given to employees: tuition reimbursement, sign-on bonus, profit sharing, CE training, promotions etc.) H. Cross-training Summary/Review Questions What was the hospital radiology department structure and function before the 1960s? The most dynamic period of growth occurred in the ….. What brought about this change? What is the difference between these references: “radiology department” and “diagnostic imaging department”? Other change(s)? What is the one consistency which remained between the old and the new system? Summary/Review Questions Explain the major differences between the old and the modern radiology departments. Who is the head of the radiology department and what are his/her functions? Who does the head of radiology report to? Name the two challenges brought to the radiology department as part of health care reform? How is cost contained in the radiology department? How do radiology departments compete with each other? DEPARTMENT OF RADIOLOGIC TECHNOLOGY & MEDICAL IMAGING RAD 1124 INTRODUCTION TO RADIOLOGIC TECHNOLOGY WEEK 5 – HC DELIVERY SYSTEM Dr. Lillian Amann, DHSc, RT (R) Learning Outcomes Discuss background and structure of the HC system Identify the three levels of care Discuss the philosophy of a hospital organization Define the principles of a mission statement List basic management principles Define concepts of TQM and QA/QC Differentiate between internal and external regulating agencies Review basics of identifying medical terminology 2 Health Care System Structure Before the mid-1800s, health care was delivered in the comfort of patients’ homes. 3 HealthofCare Structure System Structure the Health Care System In the US, institutionalization began in the mid- 19th century when large hospitals were built such as: ◆ Bellevue - in NY ◆ Cook County - in Chicago ◆ Massachusetts General – in Boston 4 Hospital System Structure Back then, health care providers attempted to alter the course of a disease process by sweating, blistering, purging and bleeding the body. The sick were placed together according to the following categories: aged, orphaned, mentally ill and physically ill; in almshouses or poor houses. Infections were treated by amputation and debridement of wounds during the civil was. 5 Health Care System Structure ❑ The medical society known today as the American Medical Association (AMA) was formed in 1847. ❑ In the mid to late 1800s, public awareness brought the need to separate the mentally ill from those with infectious and chronic diseases. 6 Health Care System Structure Medical schools trained physicians in an apprenticeship (non-academic) environment. 7 Health Care System Structure In the late 1800s to early 1900s, medical specialties were experimented with and soon became widely accepted. Today, health care is delivered through hospitals, private practice, health care clinics, centers etc. 8 Health Care System Structure As it stands, health care is delivered today on three levels: 1. Primary care 2. Secondary care 3. Tertiary care 9 3 Levels of HC Delivery Primary Care: The first contact in any given episode of illness that leads to a decision regarding a course of action to resolve a health problem. 10 3 Levels of HC Delivery Secondary Care: An intermediate level of health care that includes diagnosis and treatment is preferred in a hospital with specialized equipment and laboratory facilities. 11 3 Levels of HC Delivery Tertiary Care: A specialized, highly technical level of health care that includes diagnosis and treatment of disease and disability in sophisticated large research and teaching hospitals. 12 3-Levels of Care 13 Management Principles Fee-for-Service The traditional form of payment in which the patient or insurer pays for each doctor visit or service provided. 14 Management Principles Managed Care Use of planned and coordinated approach to providing health care with the goal of quality care at lower cost. This principle emphasizes preventive care and often associated with an HMO. 15 Management Principles Financing Orgs: An organization that finances, organizes, and provides health care using the principles of managed care. 16 Management Principles Primary Care Physician General practitioner or doctor of internal medicine who treats routine injuries and illnesses and focuses on preventive care. “Gatekeeper” for managed care. 17 Management Principles Capitation A plan that is based on per-member, per-month fixed payment to a health- care provider or health plan for each member enrolled, regardless of the amount of care a member requires. The specific services that are covered must be indicated in the plan. 18 Management Principles Deductible The amount a patient must pay out of pocket before coverage kicks in. Co-Payment A set fee paid by the patient for an office visit or other covered service (began with generally $5.00 to $15.00; now as much as $50) 19 Management Principles Centers for Medicare and Medicaid Services (CMS) Previously known as (HCFA) Part of the US Department of Health and Human Services. CMS is the contracting agency for HMOs that seek direct contractor- provider status for provisions of the Medicare benefit package. 20 21 Hospital’s Philosophy, Mission & Goals Philosophy: Hospitals’ philosophy is that wellness is a right, not just a privilege. Wellness is related to all aspects of a patient’s life. Thus, health care delivery should take a holistic approach in caring for the physical, emotional, social and economic needs of the public. 22 Hospital’s Philosophy, Mission & Goals Mission: A statement summarizing the institution’s intent to provide health care services. – “The mission of the LICH is to provide quality health care in a caring environment.” – “The mission of Louisiana State University is the generation, preservation, dissemination, and application of knowledge and cultivation of the arts for the benefit of the people of the state, the nation, and the global community.” 23 Regulating Agencies & Hospital Committees External Joint Commission on Accreditation of Health Care Organizations (JCAHO). State Health Departments Nuclear Regulatory Commission (NRC) Occupational Safety and Health Administration (OSHA) 24 Regulating Agencies & Hospital Committees Internal Committees: Safety Committee Infection Control Committee Radiation Safety Committee Pharmacy and Therapeutics Committee 25 TQM – QA & QC Total Quality management (TQM) Management of quality in the workplace from the perspective of total involvement of every employee. Quality Assurance and Quality Control Management of quality through the allocation of dedicated personnel in various departments within the organization 26 Summary Background and Structure of the Health Care System Before the mid 1800s, HC was delivered at home Institutionalization began in the mid 19th century with the building of Bellevue, Cook County and Massachusetts General Hospitals Infections were treated by amputation and debridement The AMA was formed in 1847 Physicians were trained through apprenticeship Medical specialties became widespread in the early 1900s HC is delivered today through hospitals, private clinics, HC centers and even the home 27 A Few Brain Teasers ❑ Identification of three levels of health care delivery Primary, secondary, and tertiary ❑ List of (10) Health Care Management Principles ❑ Discussion of the Hospital’s Philosophy, Mission, and Goals ❑ Regulating Agencies: Differentiate between External and Internal ❑ Concepts of TQM and QA & QC 28 TEAMWORK Makes the Dream work RAD 1124 INTRODUCTION TO RADIOLOGIC TECHNOLOGY Week 6 – HEALTHCARE TEAM Dr. Amann, DHSc, MSRS, RT (R) Teamwork in Healthcare Defined! Today’s healthcare team is an identified group of persons involved in delivering health care. This group consists of all members of the healthcare discipline. All healthcare team members contribute to the patient’s diagnosis, treatment, and possible re-attainment of health. The Healthcare Team There are over 200 healthcare careers, and each one plays an essential role as part of the healthcare system. This is especially important to provide proper patient care. Although many members of the team have no patient contact, each member individually plays a specific and important role in patient care. Failure of one or several of the many job functions results in a system breakdown. Teamwork in Healthcare Within the healthcare community, the most important people are the patients. They come to the hospital for help in preserving health or solving health-related problems. They entrust their lives to the healthcare team. Campeau’s Healthcare Team Model Healthcare Team Patient Medical Care Care Team Team Campeau’s Healthcare Team Model Team members are determined in terms of “patient contact”. This collective team is divided into two separate components. They are the patient-care team and the medical-care team. Patient Patient Care Team Care Team Members (physicians, nurses, therapists) who have the most sustained patient contact and provide individualized services related to the program of care. Medical Medical Care Team Care Team Members (radiographers, medical technologists, pathologists, pharmacists) who provide essential back-up services for the patient-care teams. These individuals have very limited contact with patients for short periods of time or perform tests without necessarily making personal contact. The Radiographer’s Role in Healthcare 1. Be a technically competent practitioner 2. Provide information through imaging 3. Eliminate the need for invasive procedures or exploratory surgery 4. Recognize and respect areas of expertise and professional role of other disciplines 5. Work compatibly or cooperate with other members of the team 6. Ability to relay information systematically and effectively to others Professional Relationships Physician/Doctor: The physician is the team leader because he/she is the one who makes the primary commitment in the patient/physician contract. Therefore, the radiographer generally follows the procedures a physician has ordered. This means that a radiographer must be presented with a signed request from a physician to proceed with a radiographic procedure. Professional Relationships The relationship between physician/radiographer involves written and oral communication as well as human respect and professional courtesy. Professional Relationships Nurses: Contact with nurses is not as frequent as contact with other technologists. However, it is important for radiographers to coordinate their work with the work of nurses wherever coordination is pertinent. Professional Relationships If, for example, a physician orders a procedure on an in-patient, the nurse must properly contact radiology and arrange radiology scheduling, patient preparation and transportation, etc. Professional Relationships The relationship between nurses/radiographer involves written and oral communications as well as human respect and professional courtesy. Professional Relationships Other Technologists: The following pertains to and includes all technologists found in the radiology department including nuclear medicine technologists, diagnostic medical sonographers, mammographers, MRI and CT technologists. They all share similar educational backgrounds in the physical sciences. Professional Relationships Other Technologists The relationship between other technologists/radiographers is that of colleagues and peers. Recent Changes in the Healthcare Team During the 1990s healthcare reform was developed and reintroduced to the health care community. This new concept deviated from “patient care orientation” to “cost-containment outcome”. It known as “patient-centered care”. In this type of healthcare delivery, there is a demand for nurses and technologists to be cross-trained in other disciplines to serve multifunction. Recent Changes in the Healthcare Team Additionally, radiographers are being called upon to step outside the boundaries of their traditional role and expand their educational base and skills. Radiographers may be required to adapt to new methodologies of delivering close and personal patient care in the near future. This will broaden the scope of practice as well. Team Approach to Healthcare Hospitals provide: Both inpatient and outpatient services Continuing education for personnel Research and prevention of disease Team approach important to better serve the patient Conditions for successful team – Clear understanding of hospital mission – Defined purpose for each role – Most importantly, provide high quality care Word Analysis Word Analysis Working in a medical setting means you are going to use medical terms daily EXAMPLE: Arthritis, electrocardiogram, hepatitis, hematology and anemia Medical words are like individual jigsaw puzzles. Once you divide the terms into their parts and learn the meaning of the individual parts, you can use that knowledge to understand many other new terms. Suffix and Root Word Word Analysis Divide the terms into their parts and learn the meaning of the individual parts. Step #1 SUFFIX: Begin at the end of the word. The suffix in hematology is – LOGY Step #2: ROOT WORD: Evaluate the beginning of the word. Provides the central meaning. Step #3: Combining Vowel which acts as a connector Putting it all Together Suffix + Root Word= Hematology: The study of blood Putting it all Together Electrocardiogram: Suffix + Root Word + Root Word Some words have two root words To Analyze: Divide the terms into their parts and learn the meaning of each part Step #1 SUFFIX: -GRAM meaning “study of” Step #2: ROOT WORD #1: -CARDI meaning “heart” and... ROOT WORD #2: -ELECT meaning ”electricity” All combined with “o” as a connecting vowel Electrocardiogram: Records the electrical signal from the heart (to check for different heart conditions) Putting it all Together (Part #2) Combining Form: The combining vowel plus the root. For Example: There are two combining forms in Electrocardiogram 1. Electr/o 2. Cardi/o Note: If the suffix begins with a vowel, The combining vowel is omitted. Example: (Arthritis) Let’s Look at Another... Gastroenterology 1. Gastr/o = Root word meaning stomach 2. Enter/o = Root word meaning intestines 3. -ology = Suffix meaning study of MEANING: Study of both the stomach and intestines Word Analysis Prefix and Root Word Divide the terms into their parts and learn the Adding the suffix –ic which means meaning of the individual parts. “pertaining to” and changing the prefix (sub, trans, retro) will give you these as Step #1 PREFIX: The prefix in examples: Subgastric is Sub- Step #2: ROOT WORD: The root word is gastric Step #3: No combining vowel needed Subgastric: Below the stomach Additional Examples PREFIX: A syllable placed before a word to alter its meaning. Example: dys/phagia = difficult swallowing dys = difficult (prefix phagia = swallowing (word root) SUFFIX: A word part that follows a word root. Example: rhinitis = inflammation of the nose rhin = word root that means nose itis = suffix that implies inflammation Example: Cholecystectomy = removal of the gallbladder. cholecyst/ ectomy = Cholecyst = word root that means gall bladder Ectomy = suffix that implies removal of Summary Questions Who makes up the health care team?

This is achieved through a clinical affiliation between hospital facilities and the college. 10/23/2024 Introduction According to the “Standards of an Accredited Educational Program for the Radiographer,” a goal of clinical education is to ensure that program graduates will competently perform a full range of radiologic procedures on children and adults. Areas of competence include head and neck, abdominal, gastrointestinal, genitourinary, bedside, and surgical procedures. 10/23/2024 Clinical Terminology Standards of an Accredited Educational Program: Document that describes the standard of quality for the educational program. 10/23/2024 Clinical Terminology Clinical: Procedures and activities that occur in the clinic or hospital setting. 10/23/2024 Clinical Terminology Three (3) Domains of Learning: Cognitive Domain One of the three major categories or domains of learning, which includes various levels of thought such as knowledge, understanding, reason, and judgment. 10/23/2024 Clinical Terminology Psychomotor Domain One of the three major categories or domains of learning, which includes behaviors involving physical actions, neuromuscular manipulations, and coordination. 10/23/2024 Clinical Terminology Affective Domain One of the three major categories or domains of learning, which includes behaviors guided by feelings and emotions that are influenced by one’s interests, attitudes, values and beliefs. 10/23/2024 Clinical Terminology Clinical Competency: Observable, successful achievement of a performance objective. 10/23/2024 Clinical Terminology Objective: Concise description of an observable behavior. Didactic: Informational and instructional activities that may occur in formal or informal settings. 10/23/2024 Clinical Terminology Direct Supervision: A radiographer is present during the entire procedure; from reviewing the request for the examination to reviewing and approving the radiographs for submission. Indirect Supervision: The radiographer is immediately available to assist the student if required, regardless of the level of student’s achievement. 10/23/2024 Clinical Terminology Repeats: Radiographs that must be repeated may only be done in the presence of a qualified radiographer, regardless of the level of student achievement. 10/23/2024 Progressive Clinical Development Clinical education is sequential, with each course building on the previous one. The first aspect of development is known as the “process”. It involves passive participation to active performance. The student progresses in the following steps: 1. Observation 2. Assistance 3. Performance 10/23/2024 Progressive Clinical Development The second aspect is known as “assessment”. This is where an instructor assesses the knowledge, comprehension and ability to apply, analyze, synthesize or evaluate specific radiographic procedures. 10/23/2024 Concepts of Clinical Environment 1. Assignment of Initials and use of Lead Markers 2. Clinical Competencies and Simulations 3. Discussion: Clinical Attendance (Signing in & out) Reporting to assigned rotation areas Preparations of room and clean-up procedure 10/23/2024 Concepts of Clinical Environment 4. Responsibilities of the Student: a. Learn about the equipment b. Learn department protocol 10/23/2024 Concepts of Clinical Environment 5. Conflict of interest: a. When orders of exam conflicts with hospital policy b. When orders from radiologist conflict with school policy c. Conflicting orders from clinical instructors and staff technologists d. Student’s rights 10/23/2024 Clinical Education Policies: 1. Clinical supervision 2. Avoidance of using students to replace staff 3. Radiation protection policies 4. Professional ethics 5.
