syngo Volume Evaluation
• Restrictions for Linking and Unlinking
There are some restrictions for linking and unlinking:
– Linking can be done on user-defined ROIs as well
as on interpolated ROIs. If you link an interpolated
ROI (dotted line), it becomes a user-confirmed ROI
(solid line).
– You cannot unlink interpolated ROIs. The unlinking
only works with user-confirmed ROIs.
– If you modify the volume (for example, move a
ROI) before linking an ROI to the already selected
ROI, the marking is reset.
• Evaluation
– Bounding voxels, where no voxel lies within the
entered range of HU values, stops region growing.
Check the depth of the volume in the coronal and
sagittal view. To complete region growing inside the
entire volume, set multiple seed points if necessary.
– You can edit the thresholds even after the volume
has been evaluated.
– You can modify or delete the last evaluated volume.
