Abstract
The present invention provides a radiotherapeutic device for irradiating X-rays in a focusing mode, which is characterized in that a plurality of X-ray generators are used for generating high-frequency X-rays to replace gamma rays to focus on pathologic change tissue; thereby the nuclear radiation in the process of nuclear distintegration is avoided. The radiotherapeutic device has the characteristics of safe use, good radiation effect and low damage to healthy tissue. The structure is further simplified.
Description
The present invention proposes a kind of device that adopts type of focusing irradiation X ray, belongs to medical radiotherapy equipment.
The radiotherapy unit of the existing employing type of focusing is to make gamma ray focusing that radioactive source produces in pathological tissues with some cobalts 60, have the health tissues damage little, the characteristics that therapeutic effect is good.Yet because the nuclear activity of cobalt 60, the nuclear defence shielding problem of its device is very outstanding, and the device and the width of cloth are penetrated focus and must be placed an anti-width of cloth of making through the employing heavy metal material of particular design and processing to penetrate bearer bar meat, thereby volume is quite huge; Because the nuclear radioactive material all being strict with, also must provide corresponding special mechanism in the device in carrying, filling, displacement.And existing X ray radiotherapy unit is to adopt single beam line direct irradiation pathological tissues.Because bigger to the health tissues damage, curative effect is relatively poor.The effect of paying is bigger, and its application is restricted.
Task of the present invention is that a kind of focusing X ray width of cloth injection device will be provided, and it is little to health tissues damage, the width of cloth is penetrated effectively, needn't adopt special shielding protection structure again.
Task of the present invention is achieved in that and the inventive system comprises a focalizer of being made up of some ray channels.This focalizer is contained in the fixed support, towards a focus point, all ray channels are all aimed at this focus point from radial direction in the focalizer, have some x ray generators to communicate with the top of these ray channels respectively, and these x ray generators are communicated with high-frequency signal source respectively again.This device places focus point with positioner with the human lesion tissue in use.The high frequency X ray suitable that each x ray generator is produced by the effect of high-frequency signal source with the gamma ray energy grade, focus on pathological tissues by ray channel and form heavy dose of concentrated width of cloth and penetrate, and the health tissues around the pathological tissues only is subjected to the low dose of dispersion width of cloth and penetrates.For further improving focusing effect, minimizing is to the infringement of health tissues, in the device that the present invention proposes, focalizer can be around the central axis revolution of intersecting with focus point in fixed support, its lonizing radiation are that the summit is scanned with the focus point, form some rotary cone focal circles, the radiation wire spoke that health tissues is subjected to is penetrated more and is disperseed.
Starting point of the present invention is that substituting cobalt 60 source with x-ray source makes radioactive source; the nuclear radiation of having avoided the nuclear decay process to produce; device needn't place the special anti-width of cloth to penetrate bearer bar; use safer; and the high frequency X ray that enters the gamma ray energy area that x ray generator produced in the device; guarantee that it has enough quantity of radiations, be aided with rational focusing configuration mode, also have the width of cloth and penetrate effective, little characteristics health tissues damage.Because x-ray source need not to fill or change the outfit, design and manufacturing also further simplify the structure.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention.
With reference to Fig. 1, in the device that present embodiment provides, focalizer (1) adopts the form that is slidingly connected to install with fixed support (2).Fixed support (2) becomes the open circles cylindricality, is a metal rack.Focalizer (1) is contained in the opening part of support (2) upper end, can in fixed support (2), do 360 degree revolutions towards focus point (0) and realize rotating focus, helping to make the suffered radiation wire spoke of health tissues to penetrate more like this disperses, also can corresponding minimizing ray channel on the structure and the number of x ray generator, make structure more compact.Consider the revolution and the focusing performance that improve focalizer (1), focalizer (1) recommends to select for use footpath, Dazhen radial ball bearing to connect with fixed support (2).The shape approximation of focalizer (1) is in a local hollow ball, use the metal material whole cast, the ray channel (3) that is installed in the focalizer (1) is aimed at focus point (0) with radial direction, at the top of ray channel (3), along the spherical outside surface of focalizer (1), the corresponding some x ray generators (4) of having installed with each ray channel (3), these x ray generators are subjected to the effect of high-frequency signal source, and energy grade is adjustable in the 1-3NEV scope, have the energy grade similar to gamma ray.Consider the convenience that is communicated with each x ray generator, high-frequency signal source (5) is directly installed on the focalizer (1).With focalizer (1) revolution, be communicated with external power by the self-cleaning contact group (6) that is installed in fixed support (2) bottom.In the present embodiment, the rotary motive power of focalizer (1) is by being installed in the external power drive mechanism of power transmission shaft (7) on focalizer (1) central axis.
Claims (4)
1, a kind of focusing X-radiation device, form by focalizer (1), fixed support (2), focalizer (1) comprises some ray channels (3) and the x ray generator (4) that communicates with ray channel (3) top, ray channel (3) is aimed at a focus point (0) from radial direction, it is characterized in that: focalizer (1) and fixed support (2) adopt and are slidingly connected, focalizer (1) in fixed support (2) around the central axis revolution of intersecting with focus point (0).
2, focusing X-radiation device according to claim 1 is characterized in that: have and the same number of high-frequency signal source of x ray generator (4) (5), and each X ray emitter (4) links to each other with high-frequency signal source (5) respectively.
3, focusing X-radiation device according to claim 2, it is characterized in that: high-frequency signal source (5) is directly installed on the focalizer (1).
4, focusing x-ray irradiation device according to claim 2 is characterized in that: high-frequency signal source (5) is communicated with external power by the self-cleaning contact group (6) of fixed support (2) bottom.
