Note
If the volume was compressed using lossy image, a yellow Wxx”, where xx stands for the
compression quality (e.g. 90) is displayed beneath the type line (e.g. 3D Static)
A lossy compression can reduce image quality, which can lead to a false diagnosis!

9.3.3 3D Color Off
On/Off switch to show an acquired 3D+CFM, 3D+PD or 3D+HD image with or without the color
information.
9.3.4 Speckle Reduction Imaging (SRI)
Speckle Reduction Imaging (SRI) can be activated to reduce speckle.
Note
If selected in System Setup - User Settings, SRI affects slices and rendered image. Therefore,
it is also active in Full Screen mode.
In addition, if SRI is activated in 2D mode, it is automatically activated in 3D/4D pre mode and
automatically affects the image after/during acquisition.
This filter smoothes the final image (structures can be smeared out).
For diagnostic, the Region of Interest must be checked without SRI filter. A smoothed image
could lead to false diagnosis!
Activate the [SRI] function and change the level of smoothing in the sectional planes using the
[+] and [-] keys on the menu area. Use of SRI is indicated in the info block. To adjust SRI got
to the Sub menu. Following menu will appear:
•
SRI: 3D Image: Filter takes effect on 3D rendered images only.
•
SRI: Slices: Filter takes effect on slice images only.
•
3D Brightness: Rotate button to set value (0 - 100), pres button to set value to 50.
•
3D Contrast: Rotate button to set value (0 - 100), pres button to set value to 50.
Remark:
•
Speckle Reduction Imaging is an option. If the option is not installed, the [SRI] key is
hidden.
