Intro to Rad Introduction to Radiologic Technology Omar Ryan D. Akalal DEGREE: NATURE OF FIELD OF STUDY: GENERAL RADIOGRAHY– An x-ray (also called general radiography) is a type of medical imaging that uses small amounts of ionizing radiation to create images of your bones, tissues and internal organs. It’s a non-invasive test that helps doctors diagnose and treat things like bone injury or disease, infections and a hritis. X-rays are the oldest and most commonly used form of medical imaging. 2 TYPES OF GENERAL RADIOGRAPHY 1. Conventional Radiography uses film and intensifying screen film in the image formation process 2. Digital imaging involves capturing radiographic images digitally using various methods like computed radiography (CR), direct radiography. Ultrasound – ultrasound is an imaging test that uses sound waves to make pictures of organs, tissues, and other structures inside your body. It allows your health care provider to see into your body without surgery. Ultrasound is also called ultrasonography or sonography A Computed Tomography (CT or CAT) scan allows doctors to see inside your body. It uses a combination of X-rays and a computer to create pictures of your organs, bones, and other tissues. It shows more detail than a regular X-ray. Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. An MRI scanner is a large tube that contains powe ul magnets. You lie inside the tube during the scan. An MRI scan can be used to examine almost any pa of the body, including the: brain and spinal cord bones and joints breasts hea and blood vessels internal organs, such as the liver, womb or prostate gland Mammogram is an X-ray image of your breasts. It can be used either for breast cancer screening or for diagnostic purposes, such as to investigate symptoms or unusual findings on another imaging test. Nuclear medicine is a medical specialty that uses radioactive tracers (radiopharmaceuticals) to assess bodily functions and to diagnose and treat disease. Specially designed cameras allow doctors to track the path of these radioactive tracers. Radiation Therapy, also called radiotherapy, is a type of cancer treatment. This treatment uses beams of intense energy to kill cancer cells. Radiation therapy most o en uses X-rays. But other types of radiation therapy exist, including proton radiation. 2 types of Radiation Therapy TELETHERAPHY BRACHYTHERAPHY Interventional Radiography - They treat a wide range of conditions in the body by inse ing various small devices, such as catheters or wires from outside the body. X- ray and imaging methods, such as CT and ultrasound help guide the radiologist. Bone Densitometry- ls called dual-energy x-ray absorptiometry, DEXA or DXA, uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower (or lumbar) spine and hips) to measure bone loss. It is commonly used to diagnose osteoporosis, to assess an individual's risk for developing osteoporotic fractures. DXA is simple, quick and noninvasive. It's also the most commonly used and the most standard method for diagnosing osteoporosis X-ray technology is an auxiliary branch of radiology which deals with the technical application of x-rays as aid in the diagnosis of diseases and injuries Radiologic technology is an auxiliary branch of radiology which deals with the technical application of radiation, such as x-rays, beta rays, gamma rays, ultrasound and radio frequency rays, in the diagnosis and treatment of diseases X-ray technologist is a bona fide holder of a ce ificate of registration for x-ray technology Radiologic Technologist is a bona fide holder of a ce ificate of registration for radiologic technology Radiology is a branch of medical science which deals with the use of radiation in the diagnosis, treatment and research of diseases Radiologist is a licensed physician who specializes in the diagnosis or treatment of disease with the use of radiation Medical physicist is a physicist who specializes in the application of the principles and techniques of physics in medicine PROGRAM GOAL: Job Description and limitation Review and evaluate developed x-rays, video tape, or computer generated information to determine if images are satisfactory for diagnostic purposes. Use radiation safety measures and protection devices to comply with government regulations and to ensure safety of patients and staff. Explain procedures and observe patients to ensure safety and comfo during scan. Operate or oversee operation of radiologic and magnetic imaging equipment to produce images of the body for diagnostic purposes. Position and immobilize patient on examining table. Position imaging equipment and adjust controls to set exposure time and distance, according to specification of examination. Key commands and data into computer to document and specify scan sequences, adjust transmi ers and receivers, or photograph ce ain images. Monitor video display of area being scanned and adjust density or contrast to improve picture quality. Monitor patients' conditions and reactions, repo ing abnormal signs to physician. Set up examination rooms, ensuring that all necessary equipment is ready. Prepare and administer oral or injected contrast media to patients. Take thorough and accurate patient medical histories. Remove and process film. Record, process and maintain patient data and treatment records, and prepare repo s. Coordinate work with clerical personnel and other technologists. Demonstrate new equipment, procedures, and techniques to staff, and provide technical assistance. Provide assistance with such tasks as dressing and changing to seriously ill, injured, or disabled patients. Move ultrasound scanner over patient's body and watch pa ern produced on video screen.
