Method used

First utilize treatment head to emit proton beam, then carry out modulation matching shaping to described proton beam, make described proton beam irradiate on the predetermined position of object, then make described proton beam realize 1: 1 imaging by magnetic lens group , and finally use the scintillator crystal and CCD camera to realize the technical scheme of real-time image acquisition, that is, adding the magnetic lens group and using the strong focusing principle of the magnetic lens to eliminate the influence of multiple Coulomb scattering, and the beamline configuration is easy to adjust and can adapt to different The energy incident protons, and the adjustment of the image contrast can also be realized through the angle collimator, the modulation and matching shaping of the proton beam, the imaging of the proton beam and the real-time acquisition of the image are all on the same rotating bracket, and the entire imaging beamline can be integrated As a whole, the relationship between each other is guaranteed, and the convenience and accuracy of use are guaranteed. Therefore, the existing proton tomography method has effectively solved the technical problems of inaccurate scanning, errors, and poor spatial resolution, and then realized the production of tomography. The scanning method has the technical effect of accurate scanning, high scanning precision, small error, and high spatial resolution.

Abstract

The invention discloses a method and device for proton tomography. The method includes the steps that firstly, proton beams are emitted through a treatment head, then the proton beams are modulated, matched and shaped, so that the preset position of an object is irradiated with the proton beams, 1:1 imaging of the proton beams is achieved through a magnetic lens set, and finally images are collected in real time through scintillating medium crystals and a CCD camera. The method and device solve the technical problems that an existing method for proton tomography is not accurate in scanning, errors exist and the spatial resolution is poor. The method for proton tomography has the technical advantages that scanning is accurate, scanning accuracy is high, the number of errors is small, and the spatial resolution is high.

Example Embodiment

[0055] Example one:
[0056] In the first embodiment, a proton tomography method is provided, please refer to Figure 1-Figure 10 , The method includes:
[0057] S10, using the treatment head to emit a proton beam;
[0058] S20: Perform modulation matching and shaping on the proton beam, so that the proton beam irradiates a predetermined part of the object;
[0059] S30, realizing 1:1 imaging of the proton beam through the magnetic lens group;
[0060] S40, using a scintillator crystal and a CCD camera to realize real-time image acquisition.
[0061] Wherein, in the embodiment of the present application, the modulation and matching shaping of the proton beam specifically includes:
[0062] Firstly, the stop is used to limit the proton beam, and the lateral emittance of the proton beam is limited to a preset range;
[0063] Then, use a beam diffuser to increase the lateral inclination of the proton;
