What is the primary purpose of temporal resolution in CT imaging?

The primary purpose of temporal resolution in CT imaging is to stop motion blur. Temporal resolution refers to the ability of the imaging system to accurately capture images over time. When there is motion, whether from the patient or from physiological processes such as breathing or heartbeat, it can lead to blur in the images. Improving temporal resolution allows for faster image acquisition, which helps to freeze motion and produce sharper, clearer images. This is particularly critical in imaging situations where motion is expected, such as with heart imaging or in patients who cannot hold still.

While enhancing contrast levels, controlling radiation dose, and improving color accuracy are important aspects of CT imaging, they do not directly address the issue of motion blur, which is specifically managed through improved temporal resolution.
