'''Tomography''' short for ''computerized axial tomography, '' a medical imaging technique that uses X-rays to produce images that resemble flat slices through the body, like those that might be made by a [[microtome]].
[[Image:CAT canner.jpg|thumb|right|250px|Medical CAT scanner]]'''Tomography''' is a method of imaging three-dimensional objects as plane sections. Three dimensional models are built up using [[electromagnetism|electromagnetic]] or acoustic [[wave]]s (such as [[x-ray]]s, [[gamma ray]]s, [[ultrasound]] or [[seismology|seismic]] waves) and processed in a [[computer]] to produce cross-sections in any desired orientation. The [[image]]s produced by tomography are known as ''tomograms''.
[[Image:CAT scan image.jpg|thumb|right|200px|CAT scan image of human torso]]In [[medicine]], x-rays may be used to image a human body by moving it through a rotating, high-speed, [[toroid]]al scanning unit. The thousands of slices are combined in a computer, this technique is known as ''computerized axial tomography'' and the machine is known as a C.A.T scanner.
