Abstract
A nuclear image processing method is provided. The method includes the following steps: inputting a normalized standard space nuclear image; selecting a voxel of the normalized standard space nuclear image and collecting the values of the neighbor voxels to form a voxel value set; conducting a data augmentation algorithm to generate a voxel distribution function; calculating an expected value of the distribution and calculating a first standard deviation of the portion over the expected value and a second standard deviation of the portion lower than the expected value; repeating the above steps to calculate the expected value, the first standard deviation and the second standard deviation of the necessary voxels, so as to form an image standardization template set including expected value template, first standard deviation template and the second standard deviation template.
