Claim 5:
6. The method for controlling a dose according to claim 5, wherein the radiation dose of the first ray corresponding to the overlapping area between the source carrier and the collimator is specifically:
in the process of aligning of the source carrier and the collimator, when the overlapping area between the source carrier and the collimator is A % of a full overlapping area, a radiation dose rate is x1% of a dose rate for the full overlapping area, x1 and A are positive integers, and the full overlapping area refers to an overlap area between the source carrier and the collimator when a collimating hole of the collimator is in-line with a radiation channel of the source carrier; and
the radiation dose of the second ray corresponding to the overlapping area between the source carrier and the collimator is specifically:
in the process of controlling the separation of the source carrier and the collimator, when the overlapping area between the source carrier and the collimator is B % of the full overlapping area, a radiation dose rate is y1% of the dose rate for the full overlapping area, and y1 and B are positive integers.
