7 3D/4D
In Accept VOI status, when the 3D image is active or the section image which is perpendicular to
the view direction is active, center point of the 3D image displays, and you can adjust the position
by rolling the trackball.
The adjustment of Rendering Parameters
In image viewing status, you can render the image by adjusting the relevant parameters.
Tap [VR] or [MPR] on the touch screen to select the VR parameter or MPR parameter.
•
When [VR] button is highlighted in green, adjust parameters of 3D image (VR).
• When [MPR] button is highlighted in green, adjust parameters of sectional image.
You can adjust:
Parameter Description
Threshold • To set the threshold for 3D image rendering.3D image is rendered on the
signal above thresholds by eliminating noise via the Threshold parameter.
Lower threshold can eliminate lower range noises and echo, which will
contribute to a clearer and smoother image.
• Available only in Surface rendering mode.
Opacity • To adjust the transparency value for 3D image rendering. It implies the
transparency of the light. The higher the value is, the tougher the surface
becomes.
• The lower the number is, the more transparent the gray scale information
will be.
• Available only in Surface rendering mode.
Smooth • To set the smoothness of 3D image.
• 0 refers to no smooth effect.
NOTE:
Insufficient smoothness can result in a fuzzy image; however, too much
smoothness will lead to image distortion.
Brightness • To set the brightness of image.
• 0% represents the minimum brightness, while 100% represents the
maximum.
NOTE:
The adjustment for 3D (VR) and MPR.
Contrast • Set the contrast scale of the image (contrast).
• As long as the contrast becomes larger, the bright spot and dark spot on
the image change as well.
NOTE:
The adjustment for 3D (VR) and MPR.
Tint Enable/disable tint map. The color of image changes according the tint value.
Quick Rotation Tap [0°], [90°], [180°], or [270°] to rotate the 3D image quickly.
