A method for establishing a geometric model based on medical images, comprising: a step of reading a medical image, a step of defining a tissue type by a conversion relationship between the medical image and the tissue type, a step of determining a number of tissue groups, and a relationship between the medical image and the density The conversion relationship defines the steps of tissue density, the steps of creating a 3D coding matrix with tissue and density information, the step of generating a geometric model, and the step of determining whether the medical image voxel is within the ROI boundary. According to the conversion relationship between medical images and tissue types, the number of organizational clusters can be set according to actual needs, and more precise information such as tissue type, element composition and density can be obtained. The geometric model established based on such information can be more matched. Medical imaging, which is closer to the actual human tissue. |
