Abstract

The invention is to create a new image modality, referred to as a map, that does not show anatomical structures, but instead indicates those image voxels where the tracked tip of the surgical instrument visited. When overlayed onto 2D or 3D greyscale anatomical images using colors or contours, the resulting map indicates where on the anatomical images the surgical instrument visited.

A METHOD AND APPARATUS FOR GENERATING A MAP THAT INDICATES LOCATIONS VISITED BY SURGICAL INSTRUMENTS

BACKGROUND OF THE INVENTION

[0001]                  With some surgical procedures, it would be beneficial to know intra-operatively and post-operatively where on the medical images (CT, MR, X-ray, etc.) the surgeons have used their medical instruments.  This would work in conjunction with surgical navigation where instead of just providing the actual position of surgical instruments, all the locations where the surgical instruments visited are recorded and displayed.  This allows surgeons to quickly determine during or after the procedure whether the necessary anatomical regions were operated on.

DETAILED DESCRIPTION OF THE INVENTION

[0002]    The invention is to create a new image modality, referred to as a map, that does not show anatomical structures, but instead indicates those image voxels where the tracked tip of the surgical instrument visited.  When overlayed onto 2D or 3D greyscale anatomical images using colors or contours, the resulting map indicates where on the anatomical images the surgical instrument visited.  Likewise, overlaying a black map of the visited points on top of CT, MR, or X-ray would suggest those regions where tissue was removed.  Displaying and archiving this map data as an image allows for it to be generated real-time, displayed real-time, and stored to media for future reference.  For revision cases, this data can be coregistered and fused to new scans thereby indicating those regions where the surgery was previously performed.  In additio...
