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.

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.

Anatomical M Mode

Allows you to move the M Mode trace in order to Image difficult -to - reach anatomy.

Sweep Speed

Changes the speed at which the time line is swept.

B Mode Control Panel Controls

Auto Optimize

Automatic Tissue Optimization optimizes the image based upon a specified Region of Interest (ROI) or anatomy within the display.

Zoom

Magnifies a zoom region of interest, which is magnified to approximately the size of a full-sized image. An un-zoomed reference image is displayed adjacent to the zoom window. The system adjusts all imaging parameters accordingly. Press Zoom key to activate. Press right zoom key again to deactivate. Use the Trackball to position the Zoom ROI.

Color Flow/Doppler Image Optimize

Baseline

Adjusts the baseline to accommodate faster or slower blood flows to eliminate aliasing.

PRF/Wall Filter

Velocity scale determines pulse repetition frequency. If the sample volume gate range exceeds single gate PRF capability, the system automatically switches to high PRF mode. Multiple gates appear, and HPRF is indicated on the display.

Wall Filter insulates the Doppler signal from excessive noise caused from vessel movement.

NOTE: Push key to toggle between PRF and Wall Filter.

Angle Correct

Estimates the flow velocity in a direction at an angle to the Doppler vector by computing the angle between the Doppler vector and the flow to be measured.

Auto Angle

Adjuste the angle to the direction of the Flow.

Angle Steer

Slants the Color Flow region of interest or the Dopple M Line to obtain a better doppler angle.

Threshold

Threshold assigns the gray scale level at which color information stops.

Doppler Display Formats

Display layout can be preset to have B-Mode and Time-motion side-by-side or over-under.

Sample Volume Gate Length

Sizes the sample volume gate.

Map

Allows a specific color map to be selected. After a selection has been made, the color bar displays the resultant map.

Packet Size

Controls the number of samples gathered for a single color flow vector.

Invert

Allows blood flow to be viewed from a different perspective, i.e. red away (negative velocities) and blue toward (positive velocities). The real-time or frozen image can be inverted.

Color Flow Control Panel Control

Scan Area

Toggles between the CFM window size and position.

Controls in Common with B Mode

For more information on Focal Zone, Power Output, FR/RES, Frame Averaging, Dynamic Range, Map, and Colorize, refer to the B/M Mode Image Optimize section in this Quick Guide on Page 6.

Scanning Hints

Line Density. Trades frame rate for sensitivity and spatial resolution. If the frame rate is too slow, reduce the size of the region of interest, select a different line density setting, or reduce the packet size.
