ABSTRACT:
A patient is secured to a subject support (10). A stereotaxic wand (40) is inserted into a tool guide (60). The wand has a tip portion (44), a portion extending along a pointing axis (46) of the wand, an offset portion (42) which is offset from the pointing axis of the wand, and at least three wand emitters (48, 50, 52), mounted in alignment with the pointing axis of the wand. The three emitters selectively emit infrared light which is received by two CCD cameras (14) mounted to a frame assembly (12). The tool guide includes a bore (76) extending along a guide axis. The bore is configured for selectively receiving a tool and the tip portion of the wand. An entry point and a trajectory are identified by the surgeon with the wand in the guide. More specifically, a trajectory and location of the wand are superimposed on a diagnostic image on a monitor (30). If the surgeon is satisfied with the entry point and trajectory shown on the monitor, a surgical tool is inserted into the bore while the tool guide is held along the designated trajectory and at the designated entry point.
