What is the only display mode that provides information regarding reflector motion with respect to time?
M-mode
With A-mode, waht does the x-axis display?
depth of the reflector
With M-mode, what does the y-axis display?
depth of the reflector
Which mode provides the foundation for real-time, grayscale anatomic imaging?
B-mode or brightness mode
With A-mode, what does the y-axis display?
