Displacement-located double-stationary-chamber double-beam proton therapy system

Abstract

The invention relates a displacement-located double-stationary-chamber double-beam proton therapy system. Based on a cyclotron, two rotary rack therapy rooms and two double-stationary-beam-therapy chambers are provided, wherein one double-fixed-beam therapy chamber is combination of a horizontal beam and a vertical beam, and the other double-fixed-beam therapy chamber is combination of a horizontal beam and a 45-degree inclined beam. Due to the double-fixed-beam combination, the number of rotary racks can be reduced, and the construction cost can be greatly reduced; and due to the structure of double fixed beams, varieties of tumors which can be treated by the fixed beams can be greatly expanded. According to the displacement-located double-stationary-chamber double-beam proton therapy layout scheme for proton therapy, the equipment occupied space can be reduced, the construction cost for proton treatment devices can be greatly reduced, and the treatment effect can be ensured.

Description

technical field [0001] The invention belongs to the technical field of biology (medical treatment), and in particular relates to a layout scheme for proton therapy, in particular to a layout of a cyclotron-based proton therapy system. Background technique [0002] Proton therapy mainly uses an accelerator to generate proton 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, they can kill cancerous cells while protecting normal tissues to the greatest extent, which makes proton therapy one of the most advanced treatments for malignant tumors in the world. [0003] Such as figure 1 As shown, in the existing proton therapy system, under normal circumstances, an accelerator will be equipped with 3 to 4 rotating racks and a fixed beam treatment head for treatment. Such a layout scheme requires a lot of constr...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, in the existing proton therapy system, under normal circumstances, an accelerator will be equipped with 3 to 4 rotating racks and a fixed beam treatment head for treatment. Such a layout scheme requires a lot of construction funds and a long construction period. The construction cost of a rotating gantry is about 100 million yuan. Such a high construction cost has also brought about an increase in treatment costs, causing a large number of patients to be "daunted" by the high cost of treatment.
