In order to realize the real time image-guided 4D prompt conformal intensity modulated radiotherapy in clinical practice using inverse optimization algorithm,the authors tested the global optimization search of the simulated annealing algorithm with a HP desk workstation and OpenMP multi thread library,which was further used for the optimization process for a virtual phantom and 4 real treatment plans of cancer patients.The results show that the method used in the test can speed up the search efficiency notably,if more CPU or core are chosen,the multi-core based parallel calculating technology can satisfy most requirements for 4D medical imaging in clinical at current time.
