Question: 1 / 615

How is temporal resolution defined in computed tomography?

The speed at which images are processed

The rate at which data are acquired

Temporal resolution in computed tomography refers to the rate at which data are acquired. This is crucial because it determines how quickly images can be captured and processed, impacting the ability to visualize fast-moving structures, such as the heart. High temporal resolution allows for better motion compensation and clearer images during dynamic processes.

The other options focus on various aspects of imaging but do not accurately define temporal resolution. The speed at which images are processed is related to post-processing capabilities rather than the fundamental concept of temporal resolution itself. The frequency of scan repetitions and the number of views collected during a scan pertain more to the overall imaging protocol rather than directly influencing how quickly data can be gathered during the scan, which is the essence of temporal resolution.
