One aspect of the present invention provides a method for establishing a geometric model based on medical image data, including: a step of reading medical image data; a step of defining tissue types through the conversion relationship between medical image data and tissue types; determining the number of tissue groups The steps; the step of defining tissue density through the conversion relationship between medical image data and density; the step of establishing a 3D coding matrix with tissue and density information; the step of generating a geometric model. In addition, a step of judging whether the medical image voxel is within the ROI boundary may also be included. According to the conversion relationship between medical image data and tissue types, the number of tissue groups can be determined according to actual needs, so as to provide more accurate tissue types, element composition and density, and the established geometric model is more in line with the reality reflected by medical image data.
