Abstract

The invention provides a design scheme for a particle beam therapeutic head device for acquiring a small beam spot. The particle beam therapeutic head device comprises scanning iron for scanning an extended particle beam, a vacuum pipeline for transmitting a scanned particle beam and a radiation protection device arranged on the vacuum pipeline. The design scheme also comprises certain necessary beam measurement and modulation devices. According to the particle beam therapeutic head device provided in the invention, the vacuum pipeline is extended near a target body from the scanning iron, andcertain necessary beam detection devices move backward. The device maintains transmission of particle beams in a low vacuum environment, the scattering effects between the beams and air can be effectively reduced, effects of a scattering angle between the beams and the detection device on the beam spot size can also be significantly reduced, and thus, a small beam spot size is maintained.

Description

technical field [0001] The invention belongs to the medical field, in particular to a particle beam treatment head device. Background technique [0002] Particle beams are often used to treat cancer in the medical field. Particle beams can kill tumor cells in the target area to the greatest extent, while minimizing damage to healthy tissues around the tumor target area, reducing the chance of complications in normal tissues, and improving the efficacy of treatment. Effect. For particle beam cancer treatment, it is generally necessary to convert the beam current into a uniform expanded beam. There are generally two methods to obtain a uniform extended beam, uniform scanning and point scanning. For uniform scanning, in order to obtain a uniform irradiation field, it is generally desired that the beam has a larger beam spot at the isocenter (ie, the central reference point of the tumor position). When the point scanning method is used, in order to achieve a good therapeutic ...
