B/M-Mode Image Optimize
Power Output
Optimizes image quality and allows user to reduce
beam intensity. 10% increments between 0-100%.
Values greater than 0.1 are displayed.
Dynamic Range
Dynamic Range controls how echo intensities are
converted to shades of gray, thereby increasing the
adjustable range of contrast.
Focus Number and Position
Increases the number of transmit focal zones or
moves the focal zone(s) 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.
NOTE: Push key to toggle between Focus Number
and Focus Position.
Virtual Convex
On Linear and Sector probes, provides a larger field
of view in the far field.
Rejection
Selects a level below which echoes will not be
amplified (an echo must have a certain minimum
amplitude before it will be processed).
Frame Average
Temporal filter that averages frames together. This
has the effect of presenting a smoother, softer
image.
Direction 2291859-100 Rev. 1
Edge Enhance
Edge Enhance brings out subtle tissue differences
and boundaries by enhancing the gray scale
differences corresponding to the edges of
structures. Adjustments to M Mode's edge
enhancement affects the M Mode only.
Colorize
Enables gray scale image colorization. To
deactivate, reselect a Gray Map.
Gray Map
Determines how the echo intensity levels received
are presented as shades of gray.
Rotation (Up/Down)
Rotates the image by selecting the value from the
pop up menu.
Coded Excitation (CE)
Improves image resolution and
penetration in the far field.
Frequency
Multi Frequency mode lets you
downshift to the probe's next lower
frequency or shift up to a higher
frequency.
Line Density
Optimizes B Mode frame rate or spatial
resolution for the best possible image.
B/M Mode
Image Optimize
B Softener
Affects amount of lateral smoothing.
Suppression
Eliminates low-level echoes associated with
acoustic/electrical noise.
B Flow Image Optimize
Provides intuitive representation of non-quantitative
hemodynamics in vascular structures.
Sensitivity/PRI
Adjusts the sample rate for the flow signal.
Background On/Off
Background On views the anatomy roadmap;
Background Off views flow information only.
