Final answer:
The imaging technique that uses X-rays to create multiple cross-sectional images is known as computed tomography (CT), which produces highly detailed two- and three-dimensional images of internal bodily structures.
Step-by-step explanation:
The imaging technique that produces multiple cross-sectional images using x-radiation is computed tomography (CT). CT scans, also known as computerized axial tomography (CAT) scans, utilize a computer to analyze several X-rays taken from different angles to create detailed cross-sectional views. This noninvasive medical imaging technology works on the principle that various structures in the body absorb or reflect X-rays to different extents. During the CT scanning process, a patient rests on a motorized platform, and the CT scanner rotates around them, capturing X-ray images from various angles. These images are then processed by a computer to form two-dimensional views of the scanned section or 'slice', allowing for highly detailed visualization of the body's internal structures. Computed tomography is capable of providing three-dimensional images and is widely used for medical diagnosis.
