Temporal resolution is related to which of the following acquisition parameters?

Temporal resolution refers to the ability of a nuclear medicine imaging system to accurately depict changes over time. It is critically important in scenarios where dynamic processes occur rapidly, such as blood flow studies or other physiological events. The framing rate specifically influences temporal resolution because it determines how frequently images are captured over a given period.

A higher framing rate allows more frames to be acquired per second, improving the system's ability to detect and represent temporal changes in the imaging data. For example, in a dynamic acquisition of blood flow, a higher framing rate would provide a more detailed analysis of how blood moves through the vessels over time.

In contrast, the other factors like percentage energy window, matrix size, and collimator primarily influence spatial resolution, sensitivity, or overall image quality, but do not directly impact the ability to capture changes over time as framing rate does. Thus, understanding the relationship between framing rate and temporal resolution is crucial for optimizing dynamic studies in nuclear medicine.
