Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0030] like figure 1As shown, the precise dose distribution modulation system in radiotherapy of the present invention includes a medical accelerator target source 1, a multi-leaf collimator 2, a pulsed KV class X-ray machine 3, an X-ray flat panel detector 4, an optical positioning system 5, Treatment couch 6, high-performance PC server 7; wherein medical accelerator target source 1 is an X-ray photon source generated by high-energy electron targeting through the bremsstrahlung effect; multi-leaf collimator 2 is used as a beam collimation device, which can adjust multiple The position of the blade sequence of the leaf grating and the movement mode of the whole machine displacement form a predetermined beam direction and beam shape treatment beam; the pulse type KV-level X-ray machine 3 and X-ray flat panel detector 4 serve as the patient's two-dimen...
