An inclusive light ion tumor treatment device

Abstract

The invention relates to a universal light ion tumor treatment device, comprising: an ion source, an ion source enclosure, an air inlet pipe, an evaporation furnace and a waveguide arranged in the housing; a linear injector, a linear injector The input end of the synchrotron is connected to the output end of the ion source through a low-energy beam line. The linear injector includes an acceleration cavity and a magnetic focusing element sleeved outside the acceleration cavity; for a synchrotron, the input end of the synchrotron is connected to a linear ion source through a medium-energy beam line. The output end of the injector is connected, and the beam input end of the synchrotron is provided with an injection cutting magnet, an injection convex rail magnet and an injection electrostatic deflection plate; the treatment terminal is connected with the synchrotron through a high-energy beam line. The device of the present invention can not only use protons for whole body therapy, but also can use 3 He, 4 He, 7 Li and other light ion beams are used for superficial (≤8cm) tumor treatment.

Description

technical field [0001] The invention relates to an inclusive light ion tumor treatment device, which belongs to the technical field of medical equipment. Background technique [0002] Because the irradiation of ion beams on organisms has an inverted depth dose distribution and a relatively high relative biological effect, it can better avoid damage to normal cells while killing tumor cells, making ion cancer treatment an advanced international technology. Effective radiation therapy for cancer. At present, the most commonly used ions for ion cancer treatment are protons and carbon ions, both of which have their own advantages and disadvantages in terms of indications and cost. [0003] Carbon ion linear energy density, relative biological effect, and side scattering advantages are more significant, and can produce DNA double-strand breaks (DSBs) that are difficult to repair, and are usually used as the best choice for cancer treatment. Above 430MeV / u, the magnetic rigidity...

Problems solved by technology

At present, the most commonly used ions for ion cancer treatment are protons and carbon ions, both of which have their own advantages and disadvantages in terms of indications and cost.

[0003] Carbon ion linear energy density, relative biological effect, and side scattering advantages are more significant, and can produce DNA double-strand breaks (DSBs) that are difficult to repair, and are usually used as the best choice for cancer treatment. Above 430MeV / u, the magnetic rigidity is relatively large, the device occupies a large area, and the investment scale is relatively high; the proton therapy device requires low magnetic rigidity, and usually uses a fixed energy accelerator, which is low in cost, relatively mature in technology, and occupies a small area. It is relatively difficult to promote in the market, but the linear energy transfer density (LET) of the proton beam is low, and it can only break the single strand of DNA, so the therapeutic effect on tumors is slightly worse
