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

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

• a scanner configured to obtain an image of a verification target radiation beam intensity modulator by scanning the verification target radiation beam intensity modulator, and to generate 3D structure information of the verification target radiation beam intensity modulator based on the image;
• and
• a verification system configured to verify the verification target radiation beam intensity modulator based on the 3D structure information of the verification target radiation beam intensity modulator and original radiation beam intensity modulator information,
• wherein the verification system comprises:
• a modulator structure reconstruction unit configured to extract thickness information of the verification target radiation beam intensity modulator based on the 3D structure information of the verification target radiation beam intensity modulator;
• an original modulator structure information receiver configured to receive structure information of the original radiation beam intensity modulator;
• a modulator matching unit configured to match the verification target radiation beam intensity modulator and the original radiation beam intensity modulator with each other based on the thickness information;
• and
• a modulator verification unit configured to verify the verification target radiation beam intensity modulator matched with the original radiation beam intensity modulator.
