A kind of Proton therapy system of double fixed chamber two-beams irradiation of dislocation arrangementTechnical field
The invention belongs to biological (medical treatment) technical fields, and in particular to a kind of placement scheme for proton therapeutic, especiallyIt is a kind of layout of Proton therapy system based on cyclotron.
Background technique
Proton therapeutic mainly utilizes accelerator to generate the proton beam of certain energy, is arrived beam transfer by each electromagnetic componentTarget area bombards tumour cell, achievees the effect that treatment.Since proton has the sharp peak Bragg in substance, can killNormal tissue is protected while dead cancerous tumor cell to the greatest extent, this makes proton therapeutic become current evil state-of-the-art in the worldOne of property oncotherapy means.
As shown in Figure 1, existing Proton therapy system, it is generally the case that an accelerator will be equipped with 3 to 4 whirlersFrame, a static-beam therapy head are treated, and construction fund needed for such placement scheme is more, and the construction period is long, and usual oneThe expenditure of construction of rotary frame is about 100,000,000 yuans, and so high expenditure of construction also brings the increase of medical expense, is causedA large amount of patient is set " to hang back " high medical expense.Therefore, it is necessary to a kind of reduction construction investment while not influencing to treatThe scheme of effect.
Summary of the invention
To solve the problems of prior art, the present invention provides a kind of construction funds for reducing proton therapeuticPlacement scheme, the program on the basis of not influencing therapeutic effect, as far as possible reduction expenditure of construction, shorten construction-time.
To achieve the above object, The technical solution adopted by the invention is as follows:
The placement scheme of double fixed chamber two-beams irradiation of the dislocation arrangement of proton therapeutic proposed by the present invention, is added in convolutionOn the basis of fast device, it are furnished with 2 rotary frame therapeutic rooms and two double static-beam therapy rooms, wherein the two double static-beam therapiesRoom, one is combined for horizontal beam with perpendicular fasciculus, and one is horizontal beam and 45 ° of inclination Shu Zuhe, and such double fixing bundle combinations subtractThe quantity for having lacked rotary frame is greatly saved expenditure of construction, meanwhile, the structure of double fixing bundles has greatly widened fixationThe medicable tumor class of beam, and to it is some it is special can not use the cases of double static-beam therapies, there are two rotate in this layoutRack therapeutic room can treat such sufferer.
The expenditure of construction of the therapeutic room of one double fixing bundle is far smaller than rotary frame therapeutic room, and about rotary frame is treatedThe half of room greatly reduces the early investment of proton therapy center to one third, while ensure that therapeutic effect.
Present invention has an advantage that double fixed chambers of the dislocation arrangement provided by according to the present invention for proton therapeutic are doubleThe proton therapeutic placement scheme of beam irradiation, reduces equipment occupation space, and greatly reduce the building expense of proton therapeutic apptsWith, while ensure that therapeutic effect.
Detailed description of the invention

Fig. 2 is Proton therapy system general illustration of the present invention.
Fig. 3 is the proton therapeutic schematic layout pattern in the present invention.
Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 2,3, double fixed chamber two-beams irradiation that the present invention provides a kind of dislocation arrangement is controlled with reducing rotary frameTreat room proton therapeutic placement scheme, the technical solution realize needed for equipment include bevatron 1 as shown in Figure 3,Proton beam transport system 2 (namely beam-flow transmission line and energy selection system in Fig. 2), rotary frame therapeutic room 3 and 4, waterFlat beam and the double static-beam therapy rooms 5 of perpendicular fasciculus, horizontal beam and the double static-beam therapy rooms 6 of 45 ° of inclination beams.
As shown in Fig. 2, the Proton therapy system further include: image guides CVCT system, and treatment planning systems, treatment is eventuallyHold turn-key system, patient positioning system.To obtain the real-time CT image in a volume range, while paramedical personnel givesThe therapeutic scheme that tumor patient is fixed for some out, and to accelerator, energy selection system, beam guide, rotationRack, treatment head, patient's positioning and colimated light system are accurately controlled and are verified.
Wherein, described image guidance CBCT system is the pencil-beam based on large area amorphous silicon Digitized X-ray detecting plateCT can be directly with the integration for the treatment of end using kV or MV grades of X-ray, and rack, which rotates a circle, can obtain and rebuild a volume modelEnclose interior CT image.
The treatment planning systems are the therapeutic scheme that tumor patient is fixed for some that medical worker provides, the programAfter being conveyed to computer, in a small amount of necessary manual decision and intervention, therapeutic device can be automatically performed therapeutic process, willCancer cell is all killed, while reducing the death of normal cell, achievees the purpose that treat tumour.
The Proton therapy system further comprise treatment terminal turn-key system, to accelerator, proton beam transport system,Rotary frame, treatment head, patient positioning system are accurately controlled and are verified.
The Proton therapy system further comprises patient positioning system, the patient positioning system including the use of visual method andPatient's coarse positioning module at laser positioning patient tumors position and the patient's essence fine-tuned using digitized image positioning systemClose collimating module.
As shown in figure 3, transmitted from the proton beam that bevatron 1 is drawn by proton beam transport system 2,In system 2, then proton beam will be transferred to rotation therapy room 3 and 4 and be consolidated by carry out energy adjustment, focusing, deflection etc.Determine in therapeutic room 5 and 6.One rotary frame is wherein respectively installed in therapeutic room 3 and 4；Therapeutic room 5 is equipped with two fixing bundles,Respectively horizontal fixing bundle and vertical fixing bundle can be irradiated patient from horizontal and vertical both direction；Therapeutic room 6Two fixing bundles are installed, 45 ° of fixing bundles of respectively horizontal fixing bundle and inclination, from horizontal and 45 ° of twocoueses to patient intoRow irradiation.Such layout reduces the construction of two rotary frames, and construction funds are greatly saved.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the artMind and range.If in this way, belonging to the model of the claims in the present invention and its equivalent technology to these modifications and changes of the present inventionWithin enclosing, then the present invention is also intended to include these modifications and variations.
