5.1.1. Using B-mode

1. Press <B> on the console to enter B mode.
2. Perform the image scanning.
3. Adjust Image parameters to optimize the image.

5.1.2. B-mode Image Optimization

The following touch controls can be used to optimize the B-mode image.

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 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.
Persistence averages frames together to reduce random
noise. There are 4 options: Off, Low, Med., and High. The
persistence level corresponds to the number of frames
averaged. The frame rate is unchanged.
Frequency allows selection of the fundamental or harmonic
frequencies used for imaging. The Harmonic option must be
invoked to access the harmonic frequencies. Frequency
selection is available during live imaging.
