What is CT? CT stands for computed tomography. A clinical CT scanner is shown in Fig. A. Figure B shows the working principle, by which x-ray beams pass through the body to be detected as projections. A set of projections across various angles forms a tomography (or a sinogram). Figure C shows a very simplistic… read more
