We describe an extension of this system to enable reviewing to occur at arbitrary points in the surgical procedure. The extension uses a combination of volume snapshots and event recording to be efficient in both time and space requirements.Categories and Subject Descriptors (according to ACM CCS): I.3.8 [Computer Graphics]: Applications J.3 [Computer Applications]: Life and Medical Sciences
