摘要：
A method and system for determining an irradiation dose. The method for determining the irradiation dose includes determining a pixel having a biological feature in a region of interest in a radiotherapy simulated locating image by using a retrospective label； extracting a local radiomics feature based on the pixel having the biological feature, in which the local radiomics feature includes a grayscale histogram intensity, a tumor shape feature, a textural feature, a Laplacian of Gaussian filtering feature, and a wavelet feature； acquiring the local radiomics features to be measured； identifying a positive region having the local radiomics features to be measured based on the local radiomics features； performing three-dimensional reconstruction for the peripheral boundary of the positive region to determine a three-dimensional image.
