The processing step further comprises the step of matching the central axis of each of the shield and the structural unit; radiation shielding manufacturing method further comprising. The method of claim 10,
The processing step may further include a removing step of forming a through part by removing an area overlapping with the structural part in the shielding part. The method of claim 8,
And a description step of writing information to the shielding unit output from the output unit. The method of claim 8,
The processing step further comprises the step of setting the thickness of the shield to correspond to the radiation energy used in the radiation treatment, from the treatment plan data, radiation shield manufacturing method.
