Abstract:
A stereotactic system comprising:an imaging display system for displaying images;an image fiducial selector coupled to the imaging display system for selecting fiducials on an image displayed on the display system;a target selector coupled to the imaging system for selecting a target on an image displayed on the display system;a spatial coordinate generator in communication with the imaging system and having a movable element, the spatial coordinate generator providing spatial coordinates of the movable element to the imaging system so that a position of the movable element is displayed on the displayed images;a patient fiducial selector operable with the imaging system and the spatial coordinate generator for selecting fiducials on a patient that correspond to the fiducials selected by the image fiducial selector;a coregistration processor for coregistering the selected patient fiducials to the selected image fiducials so that the coordinates provided by the spatial coordinate generator may be matched to the displayed images whereby a path from the movable element position to the selected target may be displayed on the displayed images; anda holder mechanically and releasably secured at a desired position in proximity to a patient, the holder having a pivot member supporting the movable element, the holder being pivotable at the desired position with respect to the patient to allow a surgeon to evaluate and establish a path as displayed on the displayed image between the desired position and the selected target, the holder having a releasable clamp to fix the holder pivot member at a desired orientation directing the movable element along the desired path.
