[0018] Invention idea of the present invention is:
[0019] A completely corresponding fusion method of preoperative CT data and intraoperative X-ray images of the present invention, such as figure 1 As shown, the 3D reconstruction of the lesion is performed using the MC algorithm based on the patient's preoperative CT3D data. The 3D reconstruction model is used as the information input, and the digital reconstruction is simulated and generated on the basis of the known dimensions of the C-arm X-ray machine to be used. For 3D image DRR images, the simulated emission source generated by the DRR image is set at the position of the real emission source of the C-arm X-ray machine, the imaging plane is set at the position of the real imaging plane of the C-arm X-ray machine, and the 3D reconstruction lesion model is located at the time of shooting. The position of the patient, so that the generation process of the DRR image can truly simulate the imaging process of the C-arm X-ra...
