Abstract: Systems and methods for automated path planning of a surgical procedure, such that the optimal approach is selected from among a series of potential choices. The system is configured to plan and carry out, using a robotic surgical system, access to a surgical site starting from selection of the skin entry point. The methods select the best surgical approach and plan the physical path for robotically performing a selected surgical procedure. The path finding method uses preoperative MRI or CT images and computer vision or other image processing method to identify specific organs and tissues. The method then assigns values to a variety of parameters that define the tissue compressibility, penetrability, flexibility, and other characteristics. The system then plans an optimal path to reach the surgical target area with minimum danger of tissue damage and maximum patient safety, and encodes this information for execution by a robotic system.

Abstract: A low radiation, intra-operative method using two-dimensional imaging to register the positions of surgical implants relative to their pre-operative planned positions. Intraoperatively, a pair of two-dimensional fluoroscope images in different planes or a single three-dimensional image is acquired and compared to a set of three-dimensional preoperative images, to allow registration of the implant region anatomy. A second set of intraoperative fluoroscope images is acquired of the surgical area with implants in place. The second set of images is compared with the first set of intraoperative images to ascertain alignment of the implants. Registration between first and second intraoperative image sets is accomplished using the implants themselves as fiducial markers, and the process repeated until an acceptable configuration of the implants is obtained. The method is particularly advantageous for spinal surgery.
