Intraoperative registration method for intraoperative image data sets, involves spatial calibration of optical three-dimensional sensor system with intraoperative imaging modality

摘要

The method involves spatial calibration of an optical 3D-sensor system with intraoperative imaging modality. Intraoperative detection of the surface of investigation area is done with 3D-sensor system. A surface is determined from a preoperative 3D-image data set containing the detected or taken surface. Intraoperative and preoperative surface mask are registered together. An image code is identified between preoperative 3D-image data set and intraoperative image data set on the basis of calibration and registration. Overlaid visualizing of intraoperative image data set is performed with the preoperative 3D-data image set on the basis of image code.
