Abstract:
An apparatus for use in delivering at least one implement to a patient in image guided surgery, comprising:an instrument location system for detecting position, the instrument location system including a computer processor; a tool guide comprising: a plurality of cannulas, each cannula having a proximal end operable to receive an implement and a distal end operable to deliver the implement to the patient, and at least one trackable marker provided on the tool guide for detection by the instrument location system; and a memory coupled to the computer processor, storing: at least one pre-acquired image of [a] the patient, the at least one pre-acquired image having an image space, and instructions, to be executed by the computer processor, to align the image space to a detector space, to track a three-dimensional position of the tool guide in the detector space, and to compute a projection of the tool guide into the at least one pre-acquired image.
