Final answer:
Helical Scanning is the CT acquisition mode during which the patient table moves between x-ray exposures.
Step-by-step explanation:
The CT acquisition mode during which the patient table moves between x-ray exposures is called Helical Scanning. Helical scanning, also known as spiral scanning, is a technique used in computed tomography (CT) where the x-ray tube and detector array rotate around the patient continuously while the patient table moves through the scanner.
This allows for the acquisition of volume data in a continuous helical pattern, resulting in faster image acquisition compared to axial scanning.
