Key Description
The B-mode key behaves differently than the other mode keys. B-mode imaging is
the baseline state of the system. Therefore, the B key returns to B-mode imaging at
any time from any display on the system. See section 5.1 for B-mode controls.
Invokes and exits strip Doppler mode. Press D button and press PW/CW on the

by the preset and can be changed while Color is active. See section 5.4 for Color

Description
The Time Gain Compensation control (TGC) adjusts the gain of the
image at different depths. Each slider can be adjusted separately,
or you can drag your finger vertically to adjust all sliders to a new
setting.
The Auto push button controls automatically updates the Overall
Gain and TGC. Each single press of the button renews the
automatic optimization.
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 image.
eSRI is Speckle Reduction Imaging. There are 4 levels: Off, Low,
Med. and High. High level provides more aggressive speckle
reduction.
