Deconstruction method of tissue element mass ratio based on medical image and construction method of geometric model

摘要

The present invention provides a method for deconstructing a tissue element mass ratio and a method for constructing a geometric model based on a medical image, and the method for deconstructing a tissue element mass ratio is based on medical image data corresponding to a known element mass ratio. Approximating a tissue element mass ratio corresponding to medical image data; a method of constructing a geometric model includes reading a medical image, defining a tissue type based on a method of deconstructing the tissue element mass ratio, Determining the number of groupings, defining the tissue density by a transform relationship between the medical image and the density, constructing a 3D encoded matrix with tissue and density information, and generating a geometric model. . By deconstructing the biological tissue element mass ratio by medical image data of a known tissue, it is possible to improve the accuracy of the dose calculation and to improve the quality of the treatment by improving the accuracy of the dose calculation when the voxel phantom is manufactured.
