• ROI and Volume Definition
– If you insert/modify an ROI, the system automati-
cally plans the ROIs on the preceding/following
images (interpolated ROIs) up to that image with
the previous/next user-defined ROI.
– User-defined ROIs have a solid contour line,
whereas interpolated ROIs have a dotted contour
line.
– When you modify an interpolated ROI (dotted
line), it becomes an user-confirmed ROI and is dis-
played with a solid line.
– The system never modifies the shape of a user-
defined ROI. In case that you insert or modify an
ROI, the shape of previous/following interpolated
ROIs may change.
– If a new ROI touches or overlaps another user-
defined ROI (solid line), the ROIs are merged dur-
ing volume calculation.
– If a new ROI touches or overlaps an interpolated
ROI (dotted line), the new ROI replaces the system
defined ROI.
