Final answer:
The CT x-ray tube rotates around the patient to generate projection views at different angles, creating detailed three-dimensional images.
Step-by-step explanation:
The CT (Computed Tomography) or CAT (Computed Axial Tomography) x-ray tube rotates around the patient to generate projection views at different angles. This process is integral to creating a detailed, cross-sectional image sequence of the patient’s body, which, when processed by a computer, can be used to construct a three-dimensional image of the scanned area. CT scans rely on the same basic radiation as standard x-rays but provide much more detailed visual information because of the multiple viewpoints and the sophisticated computer analysis.
