Final answer:
The main image quality factor affected by the difference in minimum rotation time is temporal resolution. Temporal resolution is the ability of a CT scanner to capture images quickly, without motion blur. A shorter minimum rotation time allows the scanner to capture images at a faster rate, resulting in higher temporal resolution.
Step-by-step explanation:
The main image quality factor affected by the difference in minimum rotation time is temporal resolution.
Temporal resolution is the ability of a CT scanner to capture images quickly, without motion blur. A shorter minimum rotation time allows the scanner to capture images at a faster rate, resulting in higher temporal resolution. This means that the scanner can better visualize and differentiate between moving structures, such as the beating heart.
For example, Scanner 1 with a minimum rotation time of 0.1 seconds will have a higher temporal resolution compared to Scanner 4 with a minimum rotation time of 0.4 seconds.
