IMAGING MODES

Question 1

What is A-mode?

Answer 1

Amplitude mode. Line spikes based on echo strength. X = depth, Y = amplitude.

Question 2

What is B-mode?

Answer 2

Brightness mode. Dots on grayscale, brightness = echo strength. X = depth, Z = amplitude.

Question 3

What is M-mode?

Answer 3

Motion mode. Wavy line = movement (e.g., cardiac motion). X = time, Y = depth.
