X-ray CT studies refer to imaging examinations that use X-ray computed tomography to produce cross-sectional images of an object, most commonly the human body. The technique rotates an X-ray tube and an array of detectors around the subject, collecting attenuation measurements that are reconstructed into axial slices and, by stacking, three-dimensional volumes.
The contrast in CT images arises from differences in X-ray attenuation among tissues. Detectors measure the
Computed tomography was developed in the late 1960s and early 1970s by Godfrey Hounsfield and Allan Cormack,
Applications of X-ray CT studies are wide-ranging. Clinically, they are used for neuroimaging, chest and abdominal
Safety and interpretation considerations accompany CT use. CT data are represented as voxel values, requiring trained
