Multi-photon digital therapy head

Abstract

The invention relates to a multi-photon digital treatment head, which belongs to the field of medical accelerators; because the problem of the existing two-photon treatment head is that the light field controlled by it can only be rectangular, which makes it impossible to form a non-rectangular light field. Furthermore, the desired optical field cannot be obtained accurately, and the two-photon therapeutic head has only two energy levels in the X-ray, and the set energy level cannot be changed, which has poor adaptability. The present invention uses different gold target components and fully automatic multi-leaf gratings to pass through the uniform X-ray beam, pass through the upper plate of the bearing, the shielding block, and reach the surface of the upper diaphragm component, and the front and rear directions have been set accordingly. The opening of the upper diaphragm assembly is the opening of the multi-leaf automatic grating that has been set correspondingly along the left and right directions; in the plane directly below the treatment head, the radiation field with the same size and shape as the light field can be directly obtained, which effectively solves the problem of dual The above-mentioned problems of the photon treatment head, and then realize the energy can be set arbitrarily between 6Mev-16Mev, forming a function of strong adaptability of the light field.

Description

technical field [0001] The invention relates to a treatment head, in particular to a multi-photon digital treatment head, which belongs to the field of medical accelerators. Background technique [0002] The main means of radiation therapy are medical electron linear accelerator, gamma knife, cobalt 60 treatment machine, afterloading machine and X-ray treatment machine, etc. [0003] Linear accelerators play a dominant role in various radiotherapy equipment. The installed capacity of linear accelerators in developed countries has accounted for more than 95% of the total installed capacity of radiotherapy equipment in the market. The domestic installed capacity is about 800 units, accounting for 60% of the total installed capacity of radiotherapy equipment. about. The installed capacity of linear accelerators in China is increasing at a rate of about 20% every year. It is currently dominant and will be dominant in a few years. Accelerator is an important device for modern t...

Problems solved by technology

[0005] Two-photon therapy head is widely used in foreign products, but the price is very expensive, and the requirements for the electronic equipment of the linear accelerator are relatively strict. In the process of localization, how to reduce the cost and reduce the Requirements for technology and lower requirements for electronic equipment have become the bottleneck in the localization process of medical linear accelerators;

[0006] However, the problem with the two-photon therapy head is that the light field it controls can only be rectangular, which makes it impossible to form a non-rectangular light field, and thus cannot accurately obtain the desired light field. Two energy levels, and the set energy level cannot be changed, poor adaptability

[0007] The present invention proposes a multi-photon digital treatment head, which can be set arbitrarily between 6 Mev and 16 Mev, has strong adaptability, and effectively solves the above problems. At present, there are no reports and related products at home and abroad
