Optimal dose distribution producing method for tumor irradiation, involves directly estimating adjustment of plate structure of irradiation apparatus using optimization process e.g. direct Monte Carlo optimization

摘要

The method involves directly estimating an adjustment of a plate structure of an irradiation apparatus using an optimization process e.g. simulated annealing, genetic process and direct Monte Carlo optimization. A cost function for optimization of the plate structure is adapted to a requirement of a treating physician. Basic changes in the optimization process are given by small changes in the plate structure, such that the plate structure is directly optimized. A transition probability for the basic changes in the optimization process is estimated using the cost function.
