3 3 3D SCATTERING RADIATION IMAGER RADIATION MEDICAL APPARATUS HAVING THE SAME AND METHOD FOR PLACING THE 3D SCATTERING RADIATION IMAGER

摘要

The present invention relates to a three-dimensional scattering radiation imaging apparatus capable of reconstructing radiation information that is scattered in the human body and treated as noise in the course of radiation therapy, and can discriminate the radiation irradiation position and the dose distribution using the reconstructed image, and a radiation medical apparatus . A three-dimensional scattering radiation imaging apparatus of the present invention includes a first detector for detecting the position and energy of radiation radiated from a radiation source and scattered from a target object, a second detector for detecting the position and energy of the radiation passing through the first detector, 2 detectors, and a third detector for detecting the position and energy of the radiation that has passed through the first detector, the second detector, and the third detector, and information on the position and energy of the radiation detected by the first detector, A signal processing unit for obtaining the position of the radiation source in a manner of backward tracking the direction of the radiation source, and an image processing unit for receiving the information from the signal processing unit and displaying the image as an image. The detection unit is arranged to reduce the detection uncertainty according to the scattering distribution of the incident energy of the radiation according to the Klein-Nishina formula according to the energy (E) absorbed by the object and the scattering energy. The three-dimensional scattering radiation imaging apparatus according to the present invention can detect the irradiation position and the dose distribution of the radiation in real time by the detection method using the multiple scattering technique during the radiation treatment.
