Study Notes
Introduction to Radiography
- The field of radiography is constantly evolving, with new research and experience broadening our understanding of the field.
Patient Care in Radiography
- The book covers patient care in radiography, including introduction to medical imaging.
Book Contents
- The book is divided into three parts: Introduction to Radiography, Patient Care, and Patient Care in Specific Procedures and Environments.
- Part 1 includes topics such as image quality factors, radiation effects and radiation safety, and the health care delivery system.
- Part 2 covers patient care, including professional attitudes and communications, safety, patient transfer, infection control, and patient assessment.
- Part 3 focuses on patient care in specific procedures and environments.
Introduction to Radiography Chapter
- The chapter objectives include understanding the importance of radiography and the role of the radiologic technologist.
- The chapter covers the radiographic process, including the production of x-rays and their physical nature.
Radiographic Process
- The radiographic process involves the use of electromagnetic wave radiation, with ionizing radiation used to produce radiographs.
- The x-ray tube produces x-rays, which are then directed at the patient to produce an image.
- The image receptor (IR) is used to capture the x-ray image, and is placed on the tabletop or in a tray beneath the table surface.
- The x-ray image is processed using a digital image processor to produce a digital image.
- The image is then identified with the patient's name, date, and facility name.
X-Ray Production
- The x-ray production process involves the use of x-ray equipment, including the x-ray tube.
- The chapter covers the physical nature of x-rays and their characteristics, and how they relate to the process of radiography.
Learn about the basics of radiologic technology, including the use of radiographs and radiation therapy, and the role of the IR in imaging small and large body parts.
