The detection chip can be fixed on the target object to detect the current moving state of the target object. The detection chip or the radiation generation device, both configured for wireless signal transmission to each other, can activate or deactivate the radiation emitters of the radiation generation device individually according to the current moving state of the target object and the contents of the lookup table. As the system uses wireless transmission, and the lookup table has recorded the working state of each radiation emitter in each moving state of the target object, radiotherapy can be performed without a large number of tubes or sensors. ## Claims ### Claim 1 A system for adjusting radiation target sites according to moving states of a target object, comprising: a detection chip configured to be fixed on the target object and to detect and acquire a current moving state of the target object;
