Upon receipt of the LOGIQ e and before 1st time use, it is highly recommended that the customer performs 1 full discharge / charge cycle. If the battery has not been used for > 2 months, the customers are recommended to perform 1 full discharge / charge cycle. Battery is also recommended to be stored in a shady and cool area with FCC (Full Current Capacity). One Full Discharge/Charge Cycle Process: 1. Full discharge of battery to let the LOGIQ e automatically shut down. 2. Charge LOGIQ e to 100% FCC (Full Current Capacity). 3. Discharge of LOGIQ e for complete shut down (takes 1hr for discharge). Whole process (Step1-3) will be completed around in 5 hours.

B/M Mode Image Optimize

Frame Average

B Mode Control Panel Controls

Power Output

Temporal filter that averages frames together. This has the effect of presenting a smoother, softer image.

Auto Optimize

Optimizes image quality and allows user to reduce beam intensity. 2% 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.

Colorize

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

Enables gray scale image colorization. To deactivate, reselect a Gray Map.

Zoom

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 Softkey.

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.

Sweep Speed Changes the speed at which the time line is swept. The following speed values are available, 1, 2, 3, 4, 6, 8, 12, 16.

B/M Mode Image Optimize

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 Depth/ Zoom/Ellipse key to activate Zoom. Adjust the key to increase or decrease the zoom size. Use the Trackball to position the Zoom ROI. Only when the zoom size reaches the max or press the Depth/ Zoom/Ellipse key again would deactivate the Zoom, and activate Depth.

Reverse Flips the image left/right.

B/M Mode Image Optimize (continued) B/M Mode Scanning Hints Auto Optimize. Improves imaging performance while reducing optimization time. Frequency. Changes system parameters to best optimize for a particular patient type.

Maps. There is an inter-dependency between gray maps, gain, and dynamic range. If you change a map, revisit gain and dynamic range settings. Dynamic Range. Affects the amount of gray scale information displayed. If you increase the gain, you may want to decrease the dynamic range.

B-Mode Primary Controls

Edge Enhance. Better delineates the amount of border crispness. Frame Average. Smooths the image by averaging frames. Affects the amount of speckle reduction.

LOGIQ e Quick Guide Color Flow/Doppler Image Optimize Baseline Adjusts the baseline to accommodate faster or slower blood flows to eliminate aliasing.

PRF/Wall Filter

Direction 5130174-100 Rev. 2 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.

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.

Packet Size

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

Controls in Common with B Mode

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

For more information on Focal Zone, Power Output, Frequency, Frame Average, Dynamic Range, Gray Map, and Colorize, refer to the B/M Mode Image Optimize section in this Quick Guide.

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.

Quick Angle Quickly adjust the angle by 60 degrees.

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.

Color Flow/Doppler Image Optimize

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