What is the effect of increasing imaging depth and scan line density on temporal resolution?

Explanation:
Increasing imaging depth and scan line density lengthens the time needed to acquire a single frame, so fewer frames can be captured per second. Deeper imaging means echoes from farther away take longer to reach the transducer and be processed, while more scan lines per frame add more data to collect. Together, they slow the frame rate, reducing how quickly successive images are formed. This trade-off often improves spatial detail at the expense of temporal responsiveness, so the temporal resolution is reduced.
