1. A radiation therapy system for superficial lesion treatment, comprising:
an optical scanner configured to obtain 3D scanning data of a treatment region including a superficial lesion part;
an irradiation unit configured to emit radiation to the treatment region;
a calculator configured to calculate a skin dose, energy of the radiation, and adjustment values for radiation doses according to parts based on the 3D scanning data, and generate shape data about a compensation unit provided in an end portion of the irradiation unit based on the adjustment values for the radiation doses according to the parts; and
a 3D printer configured to perform 3D printing based on the shape data to make the compensation unit,
wherein the calculator is configured to generate the shape data about the compensation unit so that a skin dose of the lesion part can be uniformized in a state that the compensation unit is spaced part from the lesion part.
