Computed Tomography (CT) scanning is a diagnostic imaging procedure that utilizes a series of narrow beams emitted through the human body as it moves in an arc. The X-ray machines that emit a single radiation beam, and CT scans produce highly detailed cross-sectional images, providing insights into tissues within solid organs. The CT scanner\'s X-ray detector captures hundreds of density levels, which are transmitted to a computer to construct 3-D images displayed on a screen.
