摘要
The present disclosure relates to a new scan technique for particle radiation therapy that may be used for cancer treatment. One embodiment relates to a method of mitigating interplay effect in particle radiation therapy in a moving target including a period of movement, where the particle radiation therapy defines a planned dose in each spot of each layer of the moving target. The method comprising dividing the planned dose in each spot into a number of spot repaintings; and generating a scan pattern for each layer by defining a beam-on time at each spot for each spot repainting, and calculating a wait time between consecutive beam-on times to distribute the spot repaintings for each spot of a respective layer are distributed over a duration of an integer number of periods of movement.
