Abstract

The invention relates to a rotating frame ion beam line layout structure and self-achromatic normal-temperature proton therapy equipment. Each of two self-achromatic units of the layout structure comprises two bending sections which are arranged in a mirror symmetry mode for deflecting a beam; at least one self-achromatic unit is an odd unit quadrupole lens group; the mirror symmetry center of theself-achromatic unit is a middle quadrupole lens; the self-achromatic unit are linearly provided with pairs of side quadrupole lenses with equal numbers; and the distances between the middle quadrupole lens and the adjacent side quadrupole lenses are the same, so that the middle quadrupole lens is used to eleminate chromatic aberration of a beam passing through the self-achromatic unit together with the two bending sections. The rotating frame ion beam line layout structure has a reasonable layout that beam lines are easy to assemble, the rotating frame ion beam line ensures that the motion trails of proton beams with different energies meet design requirements, and meanwhile, an effect of eliminating proton chromatic aberration is achieved.

Description

technical field [0001] The invention relates to the technical field of proton therapy, in particular to a beam line layout structure of a rotating frame and an auto-achromatic normal temperature proton therapy device. Background technique [0002] Proton therapy is a form of radiation therapy. After protons enter the body, a sharp dose peak (Bragg peak) is formed at the end of the range. The Bragg peak can be made to cover the tumor by adjusting the proton energy. In addition, the energy loss of protons in the incident channel is generally small, and the side scattering is also small, and the dose to the normal tissues in the front, back, left, and right is small, so it has better radiation physics performance. Beam dispersion has a detrimental effect on proton therapy and requires careful and tight control. [0003] The rotating gantry is an important part of the proton therapy equipment. The beam drawn from the cyclotron enters the rotating gantry through the transmissi...
