What improves the temporal resolution of color flow imaging?
A . Decreasing pulse repetition frequency
B . Increasing ensemble length (packet size)
C . Decreasing width of the color field of view
D . Increasing number of color lines per frame

Answer: C

Explanation:

Temporal resolution refers to the ability of the ultrasound system to distinguish events occurring closely in time. In color flow imaging, temporal resolution is affected by the frame rate, which can be increased by decreasing the width of the color field of view. This is because a narrower color field requires fewer scan lines to be processed, allowing for more frames to be captured per second.
