Embodiment 1
[0035]The preoperative planning and surgical virtual reality simulation method for minimally invasive cardiac surgery provided by the embodiment of the present invention specifically includes the following steps:
[0036] (1) Medical image data input: the system uses eFilm Workstation (Version 2.0.1) medical image processing software to preprocess the data from CT or MRI, and artificially segment two-dimensional image data sets with different enhancement phases, so that Establish a normal image coordinate system to import medical images scanned by CT, MRI, PET, etc. into the computer;
[0037] (2) Three-dimensional modeling: Using computer image processing technology, the obtained two-dimensional medical images are reconstructed into three-dimensional three-dimensional images in three-dimensional space. The 3D modeling is mainly divided into four steps: first, the data coincidence processing system is used to process the collected two-dimensional image data to obtain the forwa...
