Final answer:
A CT or CAT scan produces a computer-generated cross-sectional image in the axial plane, using multiple X-rays and computer processing to create detailed images for medical analysis.
Step-by-step explanation:
The scan that produces a computer-generated cross-sectional image in the axial plane is known as computed axial tomography (CAT), also referred to as computed tomography (CT). This medical imaging technique integrates many cross-sectional X-rays with the help of computer analysis to produce highly detailed images, often in multiple planes. The CT scanner captures slices as the patient passes through the scanner on a table, which are then processed using complex computer image processing techniques to produce a three-dimensional image of the body part being examined.
