Optimizing the Image
B-Mode Controls
B-Mode is intended to provide two-dimensional images and
measurement capabilities concerning the anatomical structure
of soft tissue.
Table 2-1: B-Mode Controls
Control Bioeffect Description/Benefit
Depth Yes Depth controls the distance over which the B-Mode images
anatomy, and the field of view. To visualize deeper structures,
increase the depth. To visualize the flatter structures, decrease the
depth.
Gain No B-Mode Gain increases or decreases the amount of echo
information displayed in an image. It may have the effect of
brightening or darkening the image if sufficient echo information is
generated.
Focus Yes Increases the number of focal zones, moves the focal zone(s) and
change the zone width so that you can tighten up the beam for a
specific area. A graphic caret corresponding to the focal zone
position(s) appears on the right edge of the image.
Whizz No Whizz will continuously optimize the brightness, contrast and
uniformity of B mode images when scanning on different tissues.
Whizz in PW/CW Doppler Mode (ASO: Auto Spectral Optimization)
optimizes the spectral data. Auto adjusts the Velocity Scale/PRF
(live imaging only), baseline shift, and invert (if preset). Upon
deactivation, the spectrum is still optimized.
Mode Cursor Yes Display the M/D cursor on the B-Mode images.
CrossXBeam Yes CrossXBeam is the process of combining three or more frames
from different steering angles into a single frame.
CrossXBeam is available on Convex and Linear probes.
CrossXBeam combines multiple co-planar images from different
view angles into a single image at real-time frame rates, using
bi-cubic interpolation.
Coded Harmonic
Imaging (Phase
Inversion Harmonic)
(CHI)
Yes Harmonic imaging utilizes Digitally Encoded Ultrasound (DEU).
Coded Harmonics enhances near field resolution for improved
small parts imaging as well as far field penetration.
Frequency Yes Switch the frequency.
