Description
Switches between grayscale and colorized (pseudo-color)
postprocessing maps.
Adjusts the current postprocessing, either grayscale or tinted.
The Dynamic Range, or log compression, adjusts how echo
intensities are converted to brightness. A high dynamic range
will display more shades of gray, while a low dynamic range will
display fewer shades of gray and a more contrasty M-mode
display.
The focus position set in B-mode applies to M-mode as well.
Upward presses move the focus shallower, regardless of the
U/D invert status of the M-mode. Downward presses move the
focus deeper.
Sweep adjusts the sweep speed of the M-mode strip. Options of
Slow, Low, Med High and
increase sweep speed. Downward presses decrease sweep
speed.
Changes the relative size of the M-mode strip compared to the
reference image. Full, large, Med and small are available.
This is an on/off control. When On, the M-Mode strip is
displayed side-by-side with the B-mode image. When Off, the
M-Mode strip is displayed below the B-mode image
The line Persistence determines how many M-mode lines are
averaged together for the display (similar to persistence in
B-Mode). Off, Low, Med and High settings are available.
Frequency determines the transmit frequency used by M-Mode.
Upward presses increase the frequency. Downward presses
decrease the frequency.
