Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] In order to solve the problem of positioning the Bragg peak in the process of proton therapy for tumors, the propagation speed of the unknown thermoacoustic signal in the human body. The invention discloses a method and equipment for determining the dosage and range of proton therapy by proton-induced thermoacoustic signals. Proton energy distribution range and therapeutic dose in the body. In this invention, it is necessary to use sensors placed at intervals along the proton irradiation direction close to the body surface of the human body to receive the thermoacoustic signal induced by th...
