Abstract

An energy regulator for protonated therapeutic apparatus is positioned between two transmission pipes and composed of a thickness-adjustable container rich of water and a thickness driven regulating mechanism. It can simplify the apparatus and reduce complex intermediate calculation in shape-adaptive scan therapy mode or rotary therapy mode as water has low influence to scattering of proton beam and can be continuously regulated easily, so having high therapeutic precision.

Description

The energy regulating system of proton therapeutic appts
The invention belongs to the medical apparatus and instruments of A61 apoplexy due to endogenous wind, it is specifically related to the energy regulating system of proton therapeutic appts.
Proton therapeutic appts is mainly by accelerator, energy regulating system, beam corridor, treat first-class composition, energy regulating system is to reduce the energy that quickens the high energy proton of generation through accelerator according to focus in the human body degree of depth and required dosage, at present, the energy-absorbing material adopts flake graphite or aluminum mostly, the proton therapeutic appts of producing as Belgian IBA company just adopts graphite to do the energy-absorbing material, the scattering coefficient of graphite and aluminum is bigger, in suitable shape scattering treatment, can utilize line to fall can the back scattering that produces tentatively expand line, but in suitable shape scanning and rotation therapy mode, require analyzer little, adopt graphite or aluminum to do and fall the energy material, just need the higher collimator of precision at the treatment head, thereby make the treatment head complicated and heavy, in addition, for improving the utilization ratio of proton, falling the caliber of the beam current tube behind the energy also usually does more greatly, and the expense of making beam current tube approximate with square being directly proportional of pipeline radius, therefore, increased manufacturing cost again.
The objective of the invention is to overcome above the deficiencies in the prior art, provide a kind of and can play accent can act on influences minimum proton therapeutic appts again to analyzer energy regulating system.
For realizing above purpose, the technical solution used in the present invention is: the energy regulating system of proton therapeutic appts, be positioned between two transmission pipelines (1), (2), comprise that energy-absorbing material (3) and thickness drive governor motion (4), it is characterized in that: energy-absorbing material (3) is a water, place also and riddle in the container, the thickness along transmission pipeline (1), (2) direction of container between two transmission pipelines (1), (2) mouthful drives under the effect of governor motion (4) adjustable at thickness.
After adopting technique scheme, because the scattering coefficient of water is very little, can not only plays and fall and can act on, also reduced influence to analyzer, therefore reduced the requirement of collimation device even can save collimator; The caliber of the transmission pipeline behind the energy falls in line need not done greatly yet, thereby reduces cost and improve the proton utilization rate; In addition, can adopt water by material because fall, and when doing treatment plan, tissue also is displaced with water, has therefore reduced complicated intermediate operations, and the treatment precision is further improved; Because water is liquid, its thickness can be realized continuously adjustable, regulates with the gear of flake graphite and aluminum and compares, and more can improve precision.
