Image Optimization 5-45
Adjust VOI
VOI On
The VR image displays VOI information.
1. In image viewing status, select [VOI] to turn it to “On.”
2. Select the desired window by tapping [A], [B] or [C] or [VR].
3. Change the VOI position, size and curved VOI if necessary.
VOI Off
The VR image displays ROI information.
When [VOI] is set as “Off”, the ROI image is displayed on the screen. Swipe the image in different
directions to observe the MPR.
Accept VOI
1. This function is usually used for MPR observation and to determine the relative position of the
MPR to the VR.
2. Select [Accept VOI] to be [On].
3. Select the desired MPR by tapping [A], [B] or [C] or [VR].
4. Swipe on the current active MPR to view the image. The other two MPRs change
correspondingly.
Image Rendering Parameters
In image viewing status, render the image by adjusting the relevant parameters.
Render setting parameters description:
Tap to select VR or MPR parameter adjustments.
When [VR] is highlighted, parameter adjustment is performed on the VR image.
When [MPR] is highlighted, parameter adjustment is performed on the MPR.
Adjustable parameters are as follows:
Function: to set the threshold for VR rendering. The VR is rendered using
the signal between the high and low thresholds.
When signals are received, from small to large, they are divided into
different levels assigned within the range of 0-100%. The threshold is a
selected range where the system filters out signals below it and above it to
render the VR image.
The lower threshold can eliminate lower range noises and echo, which
contributes to a clearer and smoother image.
Range: 0%-100%.
Available in Surface render mode only.
Function: to set the transparency value for VR rendering.
Range: 0%-100%.
The lower the number, the more transparent the grayscale information.
Available in Surface render mode only.
