Method for Manufacturing Radiation Intensity Modulating Body and Device for Manufacturing Same

An apparatus for manufacturing a radiation beam intensity modulator, the apparatus comprising:

• a radiotherapy treatment planning system configured to design a radiation beam intensity modulator according to a radiotherapy treatment plan;
• a radiation beam intensity modulator modelling system configured to model the radiation beam intensity modulator based on information about the radiation beam intensity modulator designed by the radiotherapy treatment planning system;
• and
• a three-dimensional (3D) printer configured to manufacture the radiation beam intensity modulator based on the radiation beam intensity modulator modeled by the radiation beam intensity modulator modeling system,
• wherein the radiation beam intensity modulator modeling system comprises:
• an input interface configured to obtain dose modulation information expressed as a density matrix or 3D structure information provided from the radiotherapy treatment planning system and to obtain design condition information of the radiation beam intensity modulator;
• a modulator structure generator configured to generate a radiation beam intensity modulator structure based on the design condition information of the radiation beam intensity modulator and the dose modulation information expressed as the density matrix or the 3D structure information;
• and
• a modulator structure adjustor configured to adjust the radiation beam intensity modulator structure by comparing at least one of an actual manufacturing condition and a treatment condition with the design condition information of the radiation beam intensity modulator.
