Final answer:
Tomography, and more specifically, Computed Tomography (CT) also known as a CAT scan, is the procedure where X-rays are taken from different angles to produce cross-sectional images of organs or tissues.
Step-by-step explanation:
The procedural technique in which X-rays are taken to show an organ or tissue at a particular depth is called tomography. Specifically, Computed Tomography (CT) or sometimes referred to as Computerized Axial Tomography (CAT) is the non-invasive medical imaging technique that satisfies this description. This imaging technique uses computers to analyze several X-ray measurements, from different angles, to produce cross-sectional views or "slices" of the body. A patient lies on a motorized platform, and the CAT scanner rotates 360 degrees around the patient to capture X-ray images from multiple angles. These images are then combined by a computer to form a highly detailed two-dimensional view of the scanned area. CT scans can also be used for creating three-dimensional images of an organ or tissue, offering a more detailed and function-revealing picture.
