Diagnostic Imaging Terms Flashcards
Roentgenology
X-rays
X-ray
High-energy wave that can penetrate most solid matter and present the image on photographic film
Anteroposterior View (AP view)
Positioning the patient so that the X-rays pass through the body from the anterior side to the posterior side
Barium (Ba)
Soft metallic element from the earth used as a radiopaque X-ray dye
Film
Thin sheet of cellulose material coated with a light-sensitive substance that is used in taking photographs. There is a special photographic film that is sensitive to X-rays
Film Badge
Badge containing film that is sensitive to X-rays. This is worn by all personnel in radiology to measure the amount of X-rays to which they are exposed
Lateral View
Positioning of the patient so that the side of the body faces the X-ray machine
Oblique View
Positioning of the patient so that the X-rays pass through the body on an angle
Posteroanterior View (PA view)
Positioning of the patient so that the X-rays pass through the body from the posterior side to the anterior side
Radiography
Making of X-ray pictures
Radioisotope
Radioactive form of an element
Radiologist
Physician who uses images to diagnose abnormalities and radiant energy to treat various conditions such as cancer
Radiolucent
Structures that allow X-rays to pass through; expose the photographic plate and appear as black areas on the X-ray
Radiopaque
Structures that are impenetrable to X-rays, appearing as a light area on the radiograph (X-ray)
Roentgen
Unit for describing an exposure dose of radiation
