Refer To: Basic Scan Chapter

This 3D option application is designed for qualitative information only and has no provision for any measurement or computation ability; also, no specific reconstruction resolution is provided or claimed for this option. No position information is collected for source scans used for 3D reconstructions and distortion or skewing will be introduced if frames are not acquired at a uniform rate or spacing. Also, acquiring frames by rocking the probe may create additional distortion due to the use of non-parallel source images. Remember that the 3D images created are intended for subjective evaluation only, and may have distortion that is not obvious.

Presetting Acquisition Time To preset the CINE acquisition time, 1. Press [Code P]. 2. Trackball to B Mode CINE Acquisition Time. Press Set to select. 1xNORMAL Stores every CINE frame at 30 Hz. 2xNORMAL Stores every other CINE frame at 15 Hz, etc. ACOUSTIC Samples at the acoustic firing rate on the display (recommended setting). 3. Press Exit.

Preparing the CINE Loop 1. Perform a 2D scan of the anatomy. 2. Press Freeze. Move Trackball. Click BEGIN LOOP REVIEW. 3. Edit loop size using EDIT LEFT/EDIT RIGHT softkeys. 4. Edit out extraneous frames using DELETE FRAME softkey. Click Previous/Next to access this SoftMenu. 5. Click 3D MODE softkey. 6. Use ROI Size to size and Trackball to position ROI.

Rendering the 3DView 1. Select the RECON METHOD for 3DView reconstruction. HI RES for high resolution. LO RES for low resolution. SHEAR for quick reconstruction. 2. Click Previous/Next. Select # VIEWS to be rendered, 1–18. 3. Set how to PROJECT the image. MIN enhances dark objects in B Mode. RV/MIN inverts dark objects onto white background. MAX enhances bright objects in B Mode. SURFACE enhances anatomy’s surface edges. COLOR shows just color on black background. MIN COLOR enhances color of dark objects of gray anatomy. RV/MIN COLOR inverts image (black to white background). MAX COLOR enhances bright pixel intensities to gray scale image in surrounding tissue while showing the color in vessels. 4. Specify around which AXIS to Horizontal rotate the 3DView: horizontal or vertical. 5. Select RANGE, 0/90, –45/45, 0/180, or 90/90. Vertical

Hints In Color Flow Velocity edit rendered CINE Loops, removing the frames that are not needed. Also raise the Color Threshold to increase color detail. In B Mode, select different gray maps to obtain the best contrast resolution. B-Color is also useful to improve contrast resolution.

The numbered notes below apply to the number of the exam in the table above. 1. No comments. 2. No comments. 3. No comments. 4. Depends on how the sweep of scan is performed. 5. Depends on how the sweep of scan is performed.

When vessel pulsatility is noted, increase frame averaging. If a vessel appears elongated in either direction on the 3D display, use a shorter sweep length to improve the image or edit the number of frames in the CINE Loop. Set the Frame Averaging to a higher level. When using opaque color maps, change the Color Threshold to 100%. In symmetric color maps, the Frame Average is preset to 7. The rendering time is dependent upon the number of CINE frames, size of the 3D region of interest, and choice of HI or LO RES and SHEAR reconstruction method. The longer (more frames) the CINE Loop, the greater the rendering time. The larger the 3D ROI, the greater the rendering time. For cysts, sweep in the plane with the cleanest edges. Edit the CINE Loop to include only the mass. Use high contrast maps. Activate Median Filter. The 3D rendering brings out the edges of the lesion much better than 2D. User SHEAR to quickly view the 3D volume of interest to verify that all parameters have been set correctly. On a biopsy exam, use a 0/90 angle to see the biopsy needle tracks during multiple passes into the lesion. In B Mode, select different gray maps for the best contrast resolution. B-Color may be helpful in improving the contrast resolution of the mass. Opaque maps tend to reduce noise in 3D Color Flow renderings. In Color Flow Mode, try to minimize great changes in vessel orientation. Use a symmetric velocity map (SVI) to enhance color continuity. Longer sweep lengths tend to create or appear to create greater separation of vascular structures. Choose a sweep length that most closely represents the actual sweep length. A sweep length selection larger or smaller than the actual size may cause a distortion of the anatomy. When using opaque maps, both MAX COLOR and MIN COLOR give the same result since no surrounding B Mode tissue is displayed. For Surface-rendered 3DViews, activate B-Color then adjust the window and color level to accentuate the surface of the anatomy to be rendered. Then deactivate B-Color, if desired, and render the 3DView.
