LOGIQ E9 User Guide 2-1 Direction 5180302-100 Rev. 1 Chapter 2 Performing an Exam Optimizing the Image and Measurement and Analysis
Performing an Exam 2-2 LOGIQ E9 User Guide Direction 5180302-100 Rev. 1 Optimizing the Image B-Mode Controls Table 2-1: B-Mode Controls Control Possible BioeffectDescription/ Benefit Depth Yes Depth controls the distance over which the B-Mode images anatomy. To visualize deeper structures, increase the depth. If there is a large part of the display which is unused at the bottom, 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 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. Auto Optimize No Auto Optimize (Auto) lets you optimize the image based upon a 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, in Color Flow Mode, and in Spectral Doppler. Auto in Color Flow Mode automatically adjusts the overall color gain. If you find that the gain adjustment that is automatically performed consistently results in more or less gain than you expect, then the Auto Optimize Adjustment allows you to adjust the result of the Auto feature (-5 to 5 range) so that the result more consistently matches your expectation. Auto in PW Doppler Mode optimizes the spectral data. Auto adjusts the Velocity Scale (live imaging only), baseline shift, dynamic range, and invert (if preset). Upon deactivation, the spectrum is still optimized. Mode Cursor No Displays the M/D-Mode cursor on the B-Mode image.
Optimizing the Image LOGIQ E9 User Guide 2-3 Direction 5180302-100 Rev. 1 SRI-HD No SRI-HD (Speckle Reduction Imaging High Definition) is an adaptive algorithm to reduce the unwanted effects of speckle in the ultrasound image. Image speckle usually appears as a grainy texture in otherwise uniform areas of tissue. Its appearance is related to image system characteristics, rather than tissue characteristics, so that changes in system settings, such as probe type, frequency, depth, and others, can cange the appearance of the speckle. Too much speckle can impair image quality and make it difficult to see the desired detail in the image. Likewise, too much filtering of speckle can mask or obscure desired image detail. Extra care must be taken to select the optimal SRI-HD level. SRI-HD is available in B-Mode imaging and may be used with any transducer or clinical application when image speckle appears to interfere with the desired image detail. CrossBeam No CrossBeam 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. CrossBeam 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. Frequency Yes Multi Frequency mode lets you downshift to the probes next lower frequency or shift up to a higher frequency. Steer Yes You can slant the B-Mode or Color Flow linear image left or right to get more information without moving the probe. The angle steer function only applies to linear probes. Virtual Convex Yes On Linear and Sector probes, Virtual Convex provides a larger field of view in the far field. Virtual Convex is always active with Sector probes. TGC No TGC amplifies returning signals to correct for the attenuation caused by tissues at increasing depths. TGC slide pots are spaced proportionately to the depth. The area each pot amplifies varies as well. A TGC curve may appear on the display (if preset), matching the controls that you have set (except during zoom). You can choose to deactivate the TGC curve on the image. Width Yes You can widen or narrow the size of the sector angle to maximize the images region of interest (ROI). Tilt Yes You can steer the sector angle to get more information without moving the probe while in B-Mode, M-Mode, Doppler Mode, and Color Flow Mode. Tilt is not available on Linear probes.

Performing an Exam 2-4 LOGIQ E9 User Guide Direction 5180302-100 Rev. 1 Dynamic Range No Dynamic Range controls how echo intensities are converted to shades of gray, thereby increasing the adjustable range of contrast. The Dynamic Range control name changes to Compression on frozen images. Reverse (if Preset) No Flips the image 180 degrees left/right. Line Density Yes Optimizes B-Mode frame rate or spatial resolution for the best possible image. Maps No The system supplies B, M, and Doppler Mode system maps. Frame Average No Temporal filter that averages frames together, thereby using more pixels to make up one image. This has the effect of presenting a smoother, softer image. Colorize No Colorize is the colorization of a conventional B-Mode image or Doppler Spectrum to enhance the users ability to discern B, M, and Doppler Mode intensity valuations. Colorize is NOT a Doppler Mode. NOTE: You can colorize realtime or CINE images or Timeline CINE, but not DVR images. Colorizes the gray scale image to enhance the eyes discrimination capability. Spectrum Colorize colorizes the spectrum as a function of power using the inverse of the Colorize map for the signal intensity in each Doppler line. Colorize enhances the visibility of the spectrums characteristics and enhances your ability to identify spectral broadening and the edge contours of the spectrum used to define the peak frequency/velocity. The gray bar displays while Colorize is activated. Rotation No Flips the image 180 degrees up/down. CAUTION: When reading a rotated image, be careful to observe the probe orientation to avoid possible confusion over scan direction or left/right image reversal. Rejection No Selects a level below which echoes will not be amplified (an echo must have a certain minimum amplitude before it will be processed). Suppression No Suppresses the noise in the image. LOGIQView No LOGIQView provides the ability to construct and view a static 2D image which is wider than the field of view of a given transducer. This feature allows viewing and measurements of anatomy that is larger than what would fit in a single image. Examples include scanning of vascular structures and connective tissues in the arms and legs. LOGIQView constructs the extended image from individual image frames as the operator slides the transducer along the surface of the skin in the direction of the scan plane. The quality of the resulting image is somewhat user-dependent and requires some additional skill and practice to develop proper technique and become fully proficient. LOGIQView is not available for the following: Multi Image, Timeline Modes, Color Flow Mode or PDI Mode. Table 2-1: B-Mode Controls (Continued) Control Possible BioeffectDescription/ Benefit

Available in M-Mode, Doppler Mode and M Color Flow Mode. Anatomical M-Mode Yes Anatomical M-Mode gives you the ability to manipulate the cursor at different angles and positions. The M-Mode display changes according to a motion of the M cursor.
Performing an Exam 2-6 LOGIQ E9 User Guide Direction 5180302-100 Rev. 1 Color Flow Mode Controls Table 2-3: Color Flow Mode Controls Control Possible BioeffectDescription/ Benefit Gain No Gain amplifies the overall strength of echoes processed in the Color Flow window or spectral Doppler timeline. Scale (Velocity Scale)Yes Increases/decreases the Scale on the color bar. Wall Filter No Filters out low flow velocity signals. It helps get rid of motion artifacts caused from breathing and other patient motion. Color Width Yes Color Width sizes and positions the color window. Invert (Color Invert) No Lets you view blood flow from a different perspective, e.g., red away (negative velocities) and blue toward (positive velocities). You can invert a real-time or frozen image. NOTE: Invert reverses the color map, NOT the color Scale. Baseline No Changes the Color Flow or Doppler spectrum baseline to accommodate higher velocity blood flow. Minimizes aliasing by displaying a greater range of forward flow with respect to reverse flow, or vice versa. Baseline adjusts the alias point. The default baseline is at the midpoint of the color display and at the midpoint of the color bar reference display. Angle Steer Yes You can slant the ROI of the Color Flow linear image left or right to get more information without moving the probe. The Angle Steer function only applies to linear probes. Accumulation No Accumulation enhances the flow in an image. Available in Contrast, Color Flow, and PDI. Color Flow Line DensityYes Optimizes the Color Flow frame rate or spatial resolution for the best possible color image. Map No Allows you to select a specific color map. After you have made your selection, the color bar displays the resultant map. Threshold No Threshold assigns the gray scale level at which color information stops. Frame Average No Averages color frames. Transparency Map No Brings out the tissue behind the color map. Spatial Filter No Smooths out the color, makes it look less pixely. Flash Suppression No Activates/deactivates Flash Suppression, a motion artifact elimination process. Sample Vol (Sample Vo l u m e )Yes Places the sample volume gate on the Color Flow image. The gate is positioned over a specific position within the vessel.
