ACCURACY MEASUREMENT APPRATUS OF RADIATION FOR LINAC

摘要

Disclosed is an apparatus for measuring consistency centered around radiation rotation for LINAC. The apparatus for measuring consistency centered around radiation rotation according to gantry rotation of the present invention comprises: a chamber for measuring a photon beam or electron beam; and an adjustment module having a chamber mounted thereon and installed at gantry or couch. A position of the chamber is adjusted in a direction of one or more axes by the adjustment module. According to the present invention, the apparatus for measuring consistency centered around radiation rotation for LINAC to accurately position an ion chamber at isocenter of the LINAC or to space the ion chamber apart from the isocenter by a certain distance with easy manipulation.
