Medical radiography is a broad term that covers several types of studies that require the visualization of the internal parts of the body using x-ray techniques. For the purposes of this page radiography means a technique for generating and recording an x-ray pattern for the purpose of providing the user with a static image(s) after termination of the exposure. It is differentiated from fluoroscopy, mammography, and computed tomography which are discussed elsewhere. Radiography may also be used during the planning of radiation therapy treatment. (links are to the pages in this section) It is used to diagnose or treat patients by recording images of the internal structure of the body to assess the presence or absence of disease, foreign objects, and structural damage or anomaly. During a radiographic procedure, an x-ray beam is passed through the body. A portion of the x-rays are absorbed or scattered by the internal structure and the remaining x-ray pattern is transmitted to a detector so that an image may be recorded for later evaluation. The recording of the pattern may occur on film or through electronic means.
