D . Measure movement

Answer: D

Explanation:

M-mode (Motion mode) is used in ultrasound to measure and display the movement of structures over time.

This mode is particularly useful in cardiac imaging to assess the motion of heart walls and valves. M-mode provides a one-dimensional view of the motion of tissues and is often used in conjunction with 2D imaging for a comprehensive assessment.

It is essential in evaluating the dynamic function of organs, especially in cardiology, where precise measurements of cardiac structures’ movement are crucial.
