Final answer:
Computed tomography (CT) is a noninvasive imaging technique used in medicine. It involves analyzing several cross-sectional X-rays using computers to reveal minute details about structures in the body. CT scans are created by rotating a computerized axial tomography (CAT) scanner around the patient, which takes X-ray images from different angles.
Step-by-step explanation:
Computed tomography (CT) is a noninvasive imaging technique used in medicine. It involves analyzing several cross-sectional X-rays using computers to reveal minute details about structures in the body. CT scans are created by rotating a computerized axial tomography (CAT) scanner around the patient, which takes X-ray images from different angles. These images are then combined by a computer into a two-dimensional view of the scanned area.
