4-3-4 System B/M-Mode Checks
For a basic functional check of the system’s different modes, the Quick Guide will familiarize you with
image optimization for
B-Mode, M-Mode, Color Flow, and Doppler.
Table 4-2 B/M-Mode Functions
Power Output (Acoustic Power)
Optimizes image quality and allows user to reduce beam
intensity. 2% increments between 0-100%.
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.
Rejection
Selects a level below which echoes will not be amplified (an
echo must have a certain minimum amplitude before it will be
processed).
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.
Frame Average
Temporal filter that averages frames together. This has the
effect of presenting a smoother, softer image.
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.
Frequency
Multi Frequency mode lets you
downshift to the probe's next lower
frequency or shift up to a higher
frequency.
Frame Rate/Resolution
Optimizes B Mode frame rate or spatial resolution for the best
possible image.
B Flow
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 lets you view the anatomy roadmap;
Background Off lets you view just flow information.
Sweep Speed Changes the speed at which the timeline is swept.
