Embodiment Construction
[0132] The core of the present invention is to generate a first DRR image library along the out-of-plane corner direction of the first imaging plane and a second DRR image library along the out-of-plane corner direction of the second imaging plane; The ray image is used as the registered image, and the DRR image in the first DRR image library is used as the reference image to estimate the in-plane translation parameters, in-plane rotation angle parameters and out-of-plane rotation parameters of the first X-ray image; The second X-ray image is used as the registered image, and the DRR image in the second DRR image library is used as the reference image to estimate the in-plane translation parameters, in-plane rotation angle parameters and out-of-plane rotation parameters of the second X-ray image respectively; Image registration results are obtained from the estimation results of parameters of the first X-ray image and the second X-ray image.
[0133] Firstly, the X-ray imaging...
