1. a kind of for determining the device of radiotherapy treatment planning middle dosage distribution characterized by comprisingMemory;

  • AndProcessor is coupled to the memory and is configured to;

    Multiple pen-bundle elements and multiple voxels are turned to by beam and area-of-interest are discrete respectively, determine each pen-bundle element to every individualThe dose contribution value of element;

    Determine the integral dose on each voxel with the continuously distributed of pen-bundle element according to the dose contribution value;

    AndAccording to the continuously distributed dosage distribution calculated at current vane position, wherein determined according to the dose contribution valueIntegral dose on each voxel further comprises to integral dose using fitting function with beam with the continuously distributed of pen-bundle elementThe distribution of member is fitted to obtain the integral dose on the voxel with the continuously distributed of pen-bundle element.
