Appendix E Advanced Feature Controls
Instructions for Use E - 7
Render Mode Renders the volume using the selected rendering method:
 Opacity — Smoothes image contours, creating a soft, sculptured appearance for
highlighting surface features. Uses the selections for opacity percentage, thresholds, and
smoothing.
 MinIP (Minimum Intensity Projection) — Limits the display to minimum-value pixels by
selecting pixels with the lowest value along each projection of the volume. May be helpful in
visualizing hypo-echoic lesions and large vascular structures.
 MaxIP (Maximum Intensity Projection) — Limits the display to maximum-value pixels by
selecting pixels with the highest value along each projection of the volume. May be helpful
in visualizing hyper-echoic structures and fetal skeletons.
 MeanIP (Mean Intensity Projection) — Limits the display to average-value pixels by
selecting pixels with the arithmetic mean (average) value along each projection of the
volume.
 Gradient Light — Simulates the reflection of light off a surface, resulting in improved depth
perception.
 Amnioscopic — Simulates scattering of directed light within an object, producing
translucency and shadowing effects.
 Surf. Shading — Heightens contrast, creating a textured appearance for highlighting
internal features. Uses the selected shading, opacity percentage, and thresholds.
Note: Surf. Shading is available only when CDE is activated.
Note: Only Opacity, Gradient Light, and Amnioscopic rendering modes are available when
skeletal rendering is activated.
Note: For systems without a touch screen, the selection is on the LED panel.
Format Selects a display format:
 1:1 — Displays only the selected quadrant, in full-screen display format.
 4:1 — Displays all four quadrants.
 2:1 — Displays the acquisition plane on the left of the screen and the volume on the right.
 1:3 — Displays the volume on the left of the screen and the three MPRs on the right.
Note: For systems without a touch screen, the selection is assigned to a soft key.
VOI 3-Scape Volume of Interest
Activates or deactivates the volume of interest.
 On

Low Thresh Low Threshold
Sets the low threshold for the opacity curve. Removes 2D-mode data (voxels) from the volume
that have values lower than the selected threshold.
 0 to 254
Note: For systems without a touch screen, the selection is on the LED panel.
