5.1 B-mode
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.
Name Control Description
Dynamic
Range
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
eSRI is Speckle Reduction Imaging. There are 4 levels: Off,
Low, Med. and High. High level provides more aggressive
speckle reduction.
Persistence
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
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.
Harmonic
The Harmonic control invokes and exits harmonic imaging.
While in harmonic imaging the control is highlighted and an
‘H’ is displayed in the B-mode frequency field. Depending on
the transducer, there may be multiple harmonic frequencies.
Spatial
Compounding
Spatial Compounding combines images derived from
multiple angles to reduce speckle, reduce shadow artifacts,
and enhance contrast resolution. Spatial compounding is an
on/off control.
