Abstract:
1. A system for frameless image-guided biopsy using stereoscopic imaging, the system comprising: a first preoperative imaging system for capturing a planning CT scan of a patient with stereotactic fiduciary markers to produce digitally reconstructed radiographs of the patient; a second preoperative imaging system for capturing a preoperative high resolution scan of the patient to produce target images of a tumor of the patient; a planning computer system in communication with the first and second preoperative imaging systems to fuse the digitally reconstructed radiographs of the planning CT scan with the target images of the preoperative high resolution scan to provide image data comprising target information; an operating room computer system in communication with the planning computer system to receive the image data and target information; an operating room imaging system in communication with the operating room computer system, the operating room imaging system for capturing a plurality of stereoscopic images of the patient to send to the operating room computer system wherein the plurality of stereoscopic images are fused with the image data to provide tumor location data; a six-dimensional robotic couch system configured to support the patient during use and in communication with the operating room computer system to receive tumor location data and shift position in response to infrared position data received to position the tumor of the patient at an isocenter location; a laser guidance system comprising a laser alignment mechanism mounted at least partially above the six-dimensional robotic couch system and in communication with the operating room computer system directing a plurality of alignment lasers toward the isocenter location; an optical distance indicator in communication with the operating room computer system, for optically sensing the position of the patient through the use of radiographic markers and infrared technology, and for indicating a depth of the target tumor location within the patient; and a needle positioning apparatus comprising a needle support and a needle, the needle support coupled to the six-dimensional robotic couch system and adapted to align the needle with a laser generated by the laser guidance system and directed toward the isocenter at a desired entry location, wherein the needle is adapted to be advanced to the depth of the target tumor location provided by the optical distance indicator to obtain a biopsy sample from the patient for analysis.
