Mathematical optimization model of radiation dose distribution matrix control system in cancer treatment

摘要

In this paper, we use the mathematical optimization method to design the work of the computer control system in a radiotherapy. In the models, radiation dose distribution is described by design dose matrix and we divide the matrix into different kinds of shape matrixes. We first use the therapy time as the target function and provide numbers of constraint conditions to build the initial model. Then we give two kinds of improved models based on the initial model and solve them through optimization programming.
