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.
Auto Optimize No Auto Optimize (Auto) lets you optimize the image based upon the
actual B mode image data (Auto Tissue Optimize, ATO). The
preset levels (Low, Medium and High) allow you to pick a
preference for the contrast enhancement in the resulting image.
Low does the least amount of contrast enhancement, high does the
most.
Auto is available in single or multi image, on live, frozen or CINE
images (in B-Mode only), and while in zoom and in Spectral
Doppler.
Mode Cursor No Displays the M/D-Mode cursor on the B-Mode image.
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 (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.
