programU.S.A(4)U.S.AAnd sytÈHadron beam tracking during subject hadron therapyThe invention relates to a method for tracking hadron beams during hadron therapy including a subject of tumor cells labeled with radiopharmaceuticals, wherein the hadron beams include a plurality of discrete hadron bursts, The process includes the following steps: when the explosion strikes the subject, the Compton telescope is used to detect the fast gamma ray (111) generated by the interaction between the hadron and the subject tissue, and the image of the interaction volume is reconstructed (112);Without impact, the Compton telescope was used to extract the location of radiolabeled tumor cells (121) and reconstruct the image of total tumor volume (122);The interaction volume image is compared with the total tumor volume image (131) to determine the position of the measured interaction volume relative to the measured total tumor volume.Summary chart:chart(2)
