Body Section Radiography

Body section radiography involves taking radiographs of layers of the body, that is, a series of x-rays taken at different depths in order to define images of desired areas. The desired image is brought sharply into focus while blurring out the other areas. These types of radiograms are used to locate lesions accurately in places like the lungs and bones. They are referred to as tomograms, laminograms, and planograms.


A special x-ray technique to show in detail images of structures lying in a predetermined plane of tissue while blurring or eliminating detail in images of structures in other planes. (Same as Laminography)


X-ray of a selected layer of the body made by Laminography (Picker Ultrasonic Laminograph) (See Tomography). In the early 1970's, computerized tomography (CT) was introduced into clinical medicine and revolutionized the field of diagnostic imaging.

Digital Radiography

A system which uses computers to convert the lighter and darker areas of the radiographic image into numbers and then translate these numbers into an image on a cathode ray (television) tube.
