Image Optimization 5-53
Parameter Description
Render
Gray/Inversion
Surface
Function: set Surface as 3D image rendering mode.
This is helpful for surface imaging, such as fetus
face/hand or foot.
Tips: you may have to adjust the threshold to obtain a
clear body boundary.
Max
Function: set Max as 3D image rendering mode, displays
the maximum intensity of gray values in the ROI.
This is helpful for viewing bony structures.
Min
Function: set Min as 3D image rendering mode, displays
the minimum number of gray values in the ROI.
This is helpful for viewing vessels and hollow structures.
X-ray
Function: set X-ray as 3D image rendering mode.
Displays the average value of all gray values in the ROI.
X Ray: used for imaging tissues with different structure
inside or tissues with tumor.
The above four rendering manners can be applied to both gray and
inversion modes.
Where, inversion is to inverse the grayscale of the image, so as to
enhance observation for low-echo region, applicable for vessel, cyst
and etc.
When the function is turned on, the rendering mode parameters
change into the corresponding inverse parameters.
Threshold
Function: to set the threshold for 3D image rendering. 3D image is
rendered using the signal between the high and low thresholds.
Range: 0%-100%, in increments of 1%.
Only used in surface imaging.
Transparency
Function: to set the transparency value for 3D image rendering.
Range: 0%-100%, in increments of 5%.
The higher the number, the more transparent the gray scale
information.
Only used in surface imaging.
Smooth
Function: to set the smoothness of 3D image.
Selection: 0-20. 0 refers to no smooth effect, 0-20 present 21 effects in
incremental order.
Tips: insufficient smoothness can result in a fuzzy image; however,
over smoothness will lead to image distortion.
Brightness
Function: to set the brightness of 3D image.
Range: 0%-100%, in increments of 2%. 0% presents the minimum
brightness, while 100% the maximum.
Contrast
Function: to set the contrast of 3D image.
Range: 0%-100%, in increments of 2%.
