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.
