tomograph to·mo·graph (tō'mə-grāf')
The radiographic equipment used in tomography.
Any of several radiologic techniques for making detailed three-dimensional images of a plane section of a solid object, such as the body, while blurring out the images of other planes. See also computerized axial tomography, positron emission tomography.
A procedure by which waves are sent through an object and computers produce images of cross sections of the object by using information on how the waves are changed. Both ultrasound and CAT scans are medical uses of this technique, but it is also widely used in science and industry.
