Abstract (en)

[origin: WO0219936A2] A method and system for obtaining desired subsurface views of a patient target site are disclosed. The system includes a scan-data file for storing, in digital form, volumetric scan data of a surgical site of a patient, a pointer for indicating the position and orientation of desired views, and a display screen for placement near the patient target region. A computational device operatively connected to the data file, pointer, and display screen functions to reconstruct a 2-D shadowgraph images of the patient region from the position and orientation of the pointer. By moving the pointer to selected positions and orientations, the user can view optimal and desired shadowgraph images of the patient in real time. Also disclosed is a fast-mapping algorithm for mapping volumetric data onto a two-dimensional screen, and a method and system for registering volumetric scan data of a patient surgical site with actual patient position.
