Abstract
The invention relates to a radiation treating device, which comprises: the synchronous transmission device (2) mounted on the ray protector (4), the ray beam switcher, a source carrier connected to the axle of synchronous transmission device (2), and beam limiter connected to the axles of synchronous transmission device (2) and the ray beam switcher (1). The invention has the advantages that: since the ray is focused by the space formed by rotation, the radiation dosage is concentrated on the cancer area (focus), with less hurt on the normal organism; the initial angle and final angle of ray beam are controlled, to adjust the dosage distribution on the cancer; and via layering the radiation fields of different dosages, it can meet the shape. The invention, via changing the incident angle of ray beam, reduces the hurt on normal organism; and via automatically switching ray beam, to avoid hurting the sensitive organ of patient.
Description
Technical field
The present invention relates to medical instruments field, specifically is form-adapting radiation therapy device.
Background technology
Radiotherapy is one of important means of treatment tumor, and the 60-75% tumor patient all needs to implement radiotherapy clinically.At present, be used for radiocurable method and mainly contain two big classes:
1, conventional planning treatment: as cobalt-60 therapy machine and accelerator for X-ray therapy.The plane aggregation technique that the irradiation field of several different incidence angles of general employing minority shines in the conventional planning treatment.
2, conformal radiation therapy: this technology is the mainstream technology of 21 century tumour radiotherapy, and its key character is to make the distributional pattern of high dose consistent in 3 dimension directions with the shape of tumor.Be about to radiological dose and concentrate on tumor site, the dosage of normal surrounding tissue is kept to minimum.Development has played stereotactic radiotherapy (SRT) technology based on above-mentioned requirements, as X cutter, γ cutter.They all are to adopt the non-coplane revolution space of little wild multi sphere to assemble.Irradiation field is classification, and dosage is the solid form of non-modulated in the irradiation field.Owing to have only the 2-3 kind the device structure restriction, the X cutter is more as the γ cutter.Tumor shape is different clinically, and the volume size differences is bigger sometimes, during treatment is by first shape illuminated line open country of different size tumor to be filled out fair and superposeed to finish.When the tumor shape complexity, volume often needs a lot of target spots to carry out space Rong when big to close, to reach suitable shape.The possibility of result causes normal tissue injury bigger again.In addition, body γ cutter can not change the incident direction that beam enters the patient at present, is difficult to avoid the important responsive organ of patient sometimes.Another kind is comparatively complicated conformal intensity modulated technology (IMRT), and this technology just can be finished based on clinac and dynamic multi-leaf optical grating (DMLC).Its objective is and make 3 dimension distributions of radiological dose more fit shape with 3 dimension shapes of tumor.But the equipment price of implementing this technology is very high, and manipulates complexity, and fault rate is also higher.
Summary of the invention
The object of the invention provides a kind ofly to be had the field dose distributional pattern and can adjust according to the focus shape, can carry out space-focusing again, and the treatment gross tumor volume is bigger, the cost performance height, and the suitable shape of characteristics easy to use is penetrated therapy equipment.
Form-adapting radiation therapy device of the present invention comprises: the radiation protection assembly, carry source device assembly, beam-defining clipper assembly, synchronous transmission device, beam switching device.
Carrying source device assembly comprises: carry the source device and be contained in the one group of radioactive source that carries on the device of source, radioactive source is 6-10.6-10 radioactive source is divided in the rotating shaft both sides and carries on the device of source.Carry the source device and can be bar shaped arc body, or fan type arc body.
The beam-defining clipper assembly comprises: beam-defining clipper and the calimator that is contained on the beam-defining clipper, beam-defining clipper can be whole fan-shaped arc body, or be two fan-shaped arc bodies that separate, many group calimators and a set of shield rod are housed on the beam-defining clipper, the quantity of every group of calimator, arrange with the quantity of radioactive source, arrange identical, and all aim at simultaneously more spatial (focus), the quantity of shielding rod, arrange with the quantity of radioactive source, arrange identical.
Whole beam-defining clipper can link to each other with the axle system in synchronous transmission device, the beam switching device, or two beam-defining clippers that separate respectively with synchronous transmission device, beam switching device in axle be to link to each other.
The axle system of carrying source device and synchronous transmission device links to each other.
Radiation protection assembly, year source device assembly, beam-defining clipper assembly together can be around 10-30 ° of patient's focus swing, best 20-30.
Synchronous transmission device comprises: axle or sleeve that power set link to each other.Power set comprise: motor and the decelerator that links to each other.
The beam switching device comprises: power set and the axle or the sleeve that link to each other with power set.Power set comprise: motor and decelerator.
The advantage of form-adapting radiation therapy device of the present invention is:
1, because beam (6-10 altogether) focuses on by the space multistory that rotation forms beam, make radiological dose concentrate on tumor area (focus), normal tissue injury is very little.
2, the control beam shines the initial angle and the end angle of tumor, can adjust the dose distribution of tumor site.Superpose continuously by irradiation field, reach suitable shape purpose the various dose distributional pattern.
3, by changing the angle of incidence of beam space-focusing, it is fashionable significantly to reduce at target spot Rong, to the damage of normal structure.Perhaps the important responsive organ of patient is implemented protection.
4, by the closing of automatic control beam, make patient's responsive organ injury-free.
Description of drawings
Fig. 1 is the form-adapting radiation therapy device structural representation.
But Fig. 2 is a device pendulum angle sketch map.
The specific embodiment
According to Fig. 1-shown in Figure 2, synchronous transmission device 2 and beam switching device 1 are contained on the radiation protection assembly 4, and carrying 6, one groups of radioactive sources of one group of radioactive source are housed on the source device 5 is 6-10.Carrying source device 5 is 3 to link to each other with the power set of synchronous transmission device 2 by axle, beam-defining clipper 8,9, link to each other with the power set of synchronous transmission device, beam switch device by axle system, the identical calimator 7,10 of quantity, arrangement mode of the radioactive source 6 on many groups being housed on the beam-defining clipper 8,9 and carrying source device 5, one set of shield rod also is housed simultaneously, and the quantity of shielding rod is identical with radioactive source with arrangement mode.Radioactive source 6 and calimator 7,10 are aimed at space a bit (focus) simultaneously, carry the source device and can be bar shaped arc body or fan-shaped arc body, and beam-defining clipper can be integral curved body or two arc bodies.
Carry source device 5, beam-defining clipper 8, beam-defining clipper 9 and under the driving of synchronous transmission device 2, can walk around the axis rotation of focus, thereby beam is focused at space multistory, in rotation, beam-defining clipper 8 or beam-defining clipper 9 are under the control of beam switching device 1, at any time close or the opening section beam, to change the distributional pattern of focus high dose,, the modulated field dose of difference finishes conformal intensity modulated function by being distributed to superpose.
