Description
Technical field
This utility model relates to a kind of X-ray machine, specifically, is a kind of digital X-ray machine.
Background technology
Traditional X-ray imaging utilizes cathode ray tube to send high-octane electronics, makes it strike heavy metal (generally being to use tungsten) then, and then launches x-ray, is launched by window again, sees also Fig. 1, and Fig. 1 is the X-ray machine sketch map of known technology.As shown in the figure, one X-ray tube 10, by X-ray aperture 12, penetrate x-ray, be incident upon along rectilinear direction on the human body 14 of institute's desire shooting, and at human body 14 rears, be placed with a lattice hurdle 16, the effect on lattice hurdle 16 is the scattering processes that produce when preventing the x-ray irradiation, and then makes the signal of x-ray more clear, a preceding intensifier 18 and a back intensifier 20, be positioned over the dead astern on lattice hurdle 16, be used for strengthening the intensity of x-ray imaging signal, final imaging signal is projected on the photographic film 22, show the photo result.
And the X-ray imaging mode, be utilize penetrated desire the x-ray of irradiating object, form visible image through photographic film 22, after x-ray passes the irradiation target, beat on photographic film 22, give chemical substance with power conversion, form egative film and exposure image, this simple framework has many unsatisfactory shortcomings certainly, imaging scope control as x-ray, the scope of x-ray irradiation, the scattering of x-ray etc., the imaging of traditional X-ray light ray can't be carried out portable imaging, and photographic film 22 can only use once, can't repeat to use, material is wasted very much, the cost height, this is a big shortcoming of traditional X-ray light ray, the most important thing is that the x-ray of high dose is known from experience the very big harm of generation to the people.
Therefore known traditional X-ray machine exists above-mentioned all inconvenience and problem.
Summary of the invention
The purpose of this utility model is to provide a kind of digital X-ray machine.
For achieving the above object, technical solution of the present utility model is:
A kind of digital X-ray machine comprises an x-ray generator, a scintillator and a body to be measured, wherein:
Described x-ray generator the place ahead is provided with an X-ray aperture;
Described scintillator is arranged on the rear of described X-ray aperture;
Described body to be measured is arranged between described scintillator and the described x-ray generator, and is provided with a CMOS image sensing component at described scintillator rear.
Digital X-ray machine of the present utility model can also be further achieved by the following technical measures.
Aforesaid digital X-ray machine, wherein said CMOS image sensing component is replaceable to be the CCD image sensing component.
Aforesaid digital X-ray machine wherein also comprises a radio transmission apparatus.
Aforesaid digital X-ray machine, the signal of video signal that wherein said CMOS image sensing component produces is a digital signal.
After adopting technique scheme, digital X-ray machine of the present utility model has the following advantages:
1. volume is little, and is in light weight, the efficient height.
2. reduce the radiological dose of x-ray luminous body.
3. with low cost, image sensing component is reusable.
Description of drawings
Fig. 1 is the X-ray machine sketch map of known technology.
Fig. 2 is a digital X-ray machine sketch map of the present utility model.
Fig. 3 is the sketch map of digital X-ray machine embodiment of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof this utility model is illustrated further.
The X-ray image is to comply with its penetrance imaging after the X-ray bundle penetrates object (human body) on sensitive film.The X-ray bundle can penetrate air fully, so sensitive film sensitization fully, forms the black picture (air density) on the general X-ray sheet; X-ray Shu Buneng penetrating metal, therefore sensitive film fully not sensitization form white picture (metallic density) on the X-ray sheet, each organ of human body is because the difference of X-ray bundle penetrance forms the GTG picture of the various different levels between between black and white, so each is opened X-ray sheet and has in fact comprised the X-ray that is difficult the number meter and penetrate information.When the X-ray sheet through photographic fixing, a kind of uniqueness of back formation of developing, the image of tool transparency; Under fluorescent light, under the white heat bulb, the X-ray sheet is variant because of its image that manifests of difference of transparency; When becoming miter angle or various different angles perpendicular to light source or with light source, its information that manifests is also different, that is to say that the X-ray sheet in fact is the most complicated a kind of image, if with digitized processing, it is perfect that digitized video that must the tool very high resolution just can be tending towards.
Now see also Fig. 2 and Fig. 3, Fig. 2 is a digital X-ray machine sketch map of the present utility model, and Fig. 3 is the sketch map of digital X-ray machine embodiment of the present utility model.Described x-ray generator 24 can be launched x-ray 241, and described x-ray generator 24 the place aheads are provided with an X-ray aperture 26; Described scintillator 28 contains the light stimulus material, and is arranged on the rear of described X-ray aperture 26, makes 241 dozens of x-rays that described x-ray generator 24 penetrates on described scintillator 28, can inspire visible light 281; Described body to be measured 30 is arranged between described scintillator 28 and the x-ray generator 24, and is provided with a CMOS image sensing component 32 at described scintillator 28 rears, and then the visible light 281 that inspires is imaged in described CMOS image sensing component 32.Described CMOS image sensing component is replaceable to be the CCD image sensing component, again because the signal of video signal that CMOS image sensing component 32 produces is a digital signal, be easy to image processing, can real-time continuous take, also can record a video in real time, and a radio transmission apparatus (not shown) can be connected with this CMOS image sensing component 32, carries out wireless transmission, even the CMOS making is incorporated on the chip.The built-in conditions of exposure table of APR function, as long as selection part input thickness, CMOS image sensing component or CCD image sensing component, just show conditions of exposure automatically, it is more accurate to expose, the more convenient work efficiency that significantly promotes, the x-ray of use, its dosage only need 1/20～1/30 of traditional X-ray ray machine to get final product.
Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique under the situation that does not break away from spirit and scope of the present utility model, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
