Which resolution measures the ability to track moving structures and distinguish two points in time, and is determined by frame rate?

• A. Temporal
• B. Spatial
• C. Contrast
• D. Dynamic range

Answer: (A)

Temporal resolution is about how quickly the image updates, which is governed by the frame rate. This determines how well moving structures can be tracked and whether you can distinguish two events that occur close together in time. A higher frame rate provides more frames per second, reducing motion blur and improving the ability to follow rapid movement. Spatial resolution, on the other hand, concerns the ability to distinguish small structures in space, while dynamic range deals with the range of brightness levels displayed. So the measure described—tracking motion and separating two points in time, determined by frame rate—is temporal resolution.
