Question

Which of the following correctly describes m-mode?

A) Has better axial resolution than 2D imaging
B) Uses a higher intensity beam than doppler ultrasound
C) Normally used with a sweep speed of 100 mm/s
D) Uses a very high sampling rate

Answer 1

M-mode ultrasound, also known as motion-mode ultrasound, is a type of ultrasound imaging that allows the visualization of movement in a single line.

Step-by-step explanation:

M-mode ultrasound, also known as motion-mode ultrasound, is a type of ultrasound imaging that allows the visualization of movement in a single line. It is commonly used in cardiac imaging to assess the movement of the heart's walls and valves. The correct description of m-mode ultrasound is A) Has better axial resolution than 2D imaging because it provides high resolution in the direction of the ultrasound beam.
