real-time monitoring system and method for therapeutic radiation based on plastic scintillating plate

摘要

The present invention relates to a real-time dose monitoring system and method using a plastic fluorescent plate, which is located in front of a gantry of a radiation therapy device, and transmits radiation irradiated by the radiation therapy device while generating visible light corresponding to the amount of radiation; a camera for obtaining a dose distribution map by imaging the plastic fluorescent plate; and a processor for measuring and outputting a dose based on the size and color of the visible light generation region of the dose distribution map.
