Two-photon therapy head

Abstract

The invention discloses a two-photon treatment head, comprising: a collimation cone, a treatment head rotation data device, an ionization chamber positioning mechanism, an ionization chamber, a leveler, a gold target assembly, etc.; according to actual needs, X-rays are used for treatment, and the The X-rays produced by the gold target are collimated into a cone beam through the middle cone hole of the collimation cone, and then pass through the uniformizer in the cone hole to obtain a uniform and useful X-ray beam with a uniform dose rate in the radiation plane perpendicular to the main axis of the radiation beam. , the X-ray beam passes through the through hole on the ionization chamber and the ionization chamber mechanism, and successively passes through the upper plate of the bearing, the shielding lead package, and reaches the surface of the upper diaphragm assembly, and the upper diaphragm has been set accordingly in the front and rear direction The opening of the component is the opening of the lower diaphragm component which has been set accordingly 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 is directly obtained. The invention simplifies the structure, reduces the penumbra of the field, reduces the height of the treatment head, and expands the range of the treatment head to treat patients.

Description

technical field [0001] The invention relates to a treatment head, in particular to a two-photon treatment head, and 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 treatment of ...
