Q

This medical imaging technique uses tomography where digital geometry processing is used to generate a 3D image of the internals of an object from a large series of 2D X-Ray images taken around a single axis of rotation. They may help to see tumors, blood clots, CVA, GI lesions, abdominal abscesses, biliary obstruction, aortic or cardiac aneurysms, and spinal disorders.
