A three-dimensional reconstruction system for preoperative planning of virtual operation

The invention belongs to the technical field of medical images and in particular relates to preoperative planning of a virtual operation system. The method comprises the steps of preprocessing a CT orMRI image, performing image segmentation on the denoised, smoothed and enhanced image, and performing void processing after segmentation to guarantee that the image is complete without lack of information; performing three-dimensional reconstruction on the segmented complete image. The three-dimensional reconstruction technology employs the improved MC algorithm and nine topological configurations are added to the 15 basic topological configurations in the original algorithm, so that the connection problem of the original algorithm is solved and a fitting curved surface is more complete and tends not to generate voids; finally smoothing is performed, so that the fitting curved surface is smoother and flatter; a reconstructed model can be directly applied to rear virtual operation cuttingand collision detection ap
