Description
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 hyper-echoic
structures and fetal skeletons.
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 hypo-echoic
lesions and large vascular structures.
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.
Enables or disables the specified cut plane for 2D-mode
data in the volume.
Note: This selection is not available when VOI is enabled.
Selects a processing curve that assigns echo
amplitudes to gray levels.
Note: Applies to slice quadrants only.
Controls the overall contrast resolution.
Applies the selected tint to the 2D-mode data.
Sets the low threshold for the opacity curve. Removes
2D-mode data (voxels) that have values lower than the
selected threshold.
Sets the high threshold for the opacity curve. Assigns a
constant opacity value to all voxels at or above the
selected threshold.
Note: Use Opacity instead of High Th to adjust image
transparency.
