•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.
