computerized tomography[kəm′pyüd·ə‚rīzd tə′mäg·rə·fē] (medicine) The process of producing a picture showing human body organs in cross section by first electronically detecting the variation in x-ray transmission through the body section at different angles, and then using this information in a digital computer to reconstruct the x-ray absorption of the tissues at an array of points representing the cross section. Abbreviated CT. Also known as computed tomography; computerized axial tomography (CAT). computerized tomography
computerized tomographyn. Computed tomography.computed tomography A diagnostic imaging technique in which multiple X-rays are taken from different angles in a single plane and a series of two-dimensional images (”slices”) of the different tissue densities—e.g., fat, muscle, bone, etc.—is constructed by computer. In contrast to conventional radiology, CT results in a 1000-fold increase in image resolution, and can pinpoint lesions < 2 mm in greatest dimension; dyes may be injected IV to increased resolution of abnormal tissue and blood vessels, or radiocontrast can be used for dynamic testing.FinancialSeeCTAcronymsSeecourtcomputerized tomography
