Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 Shown is a cyclotron-based proton therapy system provided by the present invention, the system includes a proton cyclotron 1 and a main proton beam transport system 2 for transporting protons in the proton cyclotron, the main proton beam transport System 2 transmits the protons with the required energy to the treatment rooms on three different paths through the switch magnet 6 respectively. The treatment rooms on the three different paths are the treatment room 3 on the rotating gantry and the horizontal treatment room on both sides of the treatment room 3 on the rotating gantry. beam and vertical beam double fixed beam treatment room 4 and horizontal beam and inclined beam double fixed beam treatment room 5. The inclined beam in the double fixed beam treatment room 5 of the horizontal beam and t...

Abstract

The invention relates to a proton treatment system based on a cyclotron, which includes a proton cyclotron (1) and a main proton beam transport system (2) for conveying protons in the proton cyclotron. The main proton beam transport system (2) respectively conveys the protons with required energy to three treatment rooms with different paths through a switch magnet (6). The three treatment rooms with different paths include a rotary frame treatment room (3), a horizontal beam-vertical beam double-fixing-beam treatment room (4) and a horizontal beam-incline beam double-fixing-beam treatment room (5), wherein the horizontal beam-vertical beam double-fixing-beam treatment room (4) and the horizontal beam-incline beam double-fixing-beam treatment room (5) are arranged at both sides of the rotary frame treatment room (3). The occupation space of a proton treatment device is reduced and the construction cost of a proton treatment apparatus is lowered by employing the proton treatment system. The proton treatment system based on the cyclotron has the compact structure and guarantees the treatment effect.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a proton therapy system based on a cyclotron. Background technique [0002] At present, the incidence of cancer in our country is getting higher and higher, and it has become one of the biggest killers that endanger the health of our people. The usual treatment methods include surgery, gamma knife, proton / heavy ion therapy, etc. [0003] Proton / heavy ion therapy mainly uses accelerators to generate proton / heavy ion beams with a certain energy, and transmits the beams to the target area through various electromagnetic components to bombard tumor cells to achieve therapeutic effects. Because protons have sharp Bragg peaks in substances, that is, their energy will be lost to the cancerous position to the greatest extent, so it can kill cancerous cells while protecting normal tissues to the greatest extent, which makes proton therapy the most advanced in the world. It is...
