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.
