Verification equipment of target point and dose distribution for stereotactic brain radiosurgery

摘要

PURPOSE: A target of brain stereotactic radio-surgery and a verifying device of radiation distribution are provided to copy a tumor to be a target of radio-surgery and to confirm 3D radiation distribution by using a gel instrument. CONSTITUTION: An anatomical phantom(110) has radio transparent. Liquid filler(111) is filled in a cavity(110a) of the phantom. A plurality of gel instruments(120) is arranged in order to be respectively corresponded to a verification object location. A bottom plate(130) comprises a plurality of insertion holes. A plurality of receiving parts(140) respectively accepts the gel instrument in inside. One end of a plurality of connection parts(150) is respectively inserted into the insertion hole of the bottom plate. The other end of a plurality of connection parts is connected to the receiving part. A sealing part(160) seals the cavity of the phantom.
