Parameter determination method and device, computer equipment and storage medium

Abstract

The invention relates to a parameter determination method and device, computer equipment and a storage medium. The method comprises the following steps: obtaining first parameter distribution by using pre-established normal tissue parameter distribution and to-be-processed target medical image data; processing the target medical image data by using a pre-trained region segmentation model to obtain target information corresponding to the target medical image data; the target information comprises a target area where a focus is located; determining second parameter distribution corresponding to the target area in a pre-established abnormal organization parameter retrieval table; and determining target parameter distribution corresponding to the target medical image data according to the first parameter distribution and the second parameter distribution. By adopting the method, the determination difficulty of the parameter initial value and the boundary condition can be reduced, and the problem that the performance and the accuracy of an optimization algorithm are affected due to poor determination of the initial value and the boundary condition is avoided.
