Description
Enable a mirror image of the 2D image to be created. The
reference marker W moves correspondingly to the other
side of the image. Up/Down is available in both Live and
Freeze.
Adjust the horizontal refresh rate of M-Mode area display.
You can speed up or slow down the time line to observe
how often an specific event occurs.
Toggles the display layout of the 2D area and M-mode
area, either top/bottom or side by side.
Use the Focus control to center the focal point(s) on the
region of interest. Along the entire depth, the focused
position has the most optimal signal strength and resolu-
tion. Moving the focus position will improve correspond-
ing positional signal.
Description
Enables control of the dynamic range or contrast of the
image. When dynamic range is set high, the image is
softer.
Gray scale map can improve image contrast resolution,
noise suppression, and display effects. Map is available in
both Live and Freeze.
Control and adjust the image tint. Tint is available in both
Live and Freeze.
Controls the amount of acoustic power applied in all
modes. When power is set to maximum, it is equal to or
less than the maximum acoustic power permitted by the
FDA. When power is reduced, the signal-to-noise ratio
decreases, resulting in potentially noisier image.
Description
Adjusted by the knob below the TGC on the control panel.
When rotated clockwise, increases the overall gain applied
to the received echo signals equally for all depth.
Compensates for depth-related attenuation in an image.
The sliders nearest the operator affect the far field. TGC
amplifies returning signals to compensate for the attenua-
tion caused by tissue at increasing depths.
