Abstract
The invention relates to a high-sensitivity imaging chain system. After X rays emitted from an X ray source pass through an object to be detected, and are converted into monochromatic visible light by an image intensifier through image intensifying; the visible light is imaged on a digital camera through a lens, is transmitted to a computer by an image acquisition card, and is processed by an image processing software to obtain a corresponding detection image. The high-sensitivity imaging chain system provided by the invention utilizes the image intensifier combined by an intensifying screen and a low light level image intensifier, so that the field of view of imaging is large, the imaging speed is quick, the imaging sensitivity is improved, and clear and high-resolution high-quality images can be obtained.
Description
Technical field
The invention belongs to the medical imaging field, relate in particular to a kind of high sensitivity image catenary system.
Background technology
The image chain, together with imaging sensor, refer to a kind of process with light path, comprises and utilize sensing data to carry out reconstructed image, and the color of matching image, noise reduction and sharpening etc., to form the picture of a panel height quality.In x-ray imaging system, mainly utilize booster to convert sightless radioscopic image to visible images, and brightness of image is strengthened; The medical system set up based on x ray image intensifier, lowered patient's suffered X-radiation dosage when diagnosis, greatly because applied widely.But the brightness of image of the visible ray that existing image amplifier produces is very low, picture quality is not high, and visual field is little, and image taking speed is fast not, and sensitivity is not high; And the quality that strengthens image is the study hotspot of this area always.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the image catenary system that a kind of field range is large, highly sensitive, image taking speed fast, image quality is higher is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of high sensitivity image catenary system, it is characterized in that: the X ray penetrated from x-ray source is through determinand, carry out the figure image intensifying and convert X-ray to monochromatic visible light by image amplifier, scioptics by visual light imaging on digital camera, be transferred on computer by image pick-up card, then processed by image processing software, obtain corresponding detected image.
In a preferred embodiment of the present invention, further comprise that described image amplifier is coupled to form through electrostatic lenses by intensifying screen and gleam image intensifier, described intensifying screen is in order to increase the photon numbers of X ray, and described gleam image intensifier is in order to strengthen the photon luminance of X ray.
In a preferred embodiment of the present invention, further comprise that described X ray is penetrated by the high-frequency X-ray source.
In a preferred embodiment of the present invention, further comprise that described lens are the LED optical lens.
In a preferred embodiment of the present invention, further comprise that described visible wavelength is 540nm.
In a preferred embodiment of the present invention, further comprise described digital camera be CCD the CMOS camera.
The invention solves the defect existed in background technology, the image amplifier that high sensitivity image catenary system provided by the invention utilization is combined into as the sensitizing device by intensifying screen and low-light, can make that the visual field scope is large, image taking speed is fast, improve imaging sensitivity, can obtain the high quality image clear, that resolution is high.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is system structural framework figure of the present invention;
Fig. 2 is the structural representation of booster in the present invention.
The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of high sensitivity image catenary system, the X ray penetrated from x-ray source is through determinand, carry out the figure image intensifying and convert X-ray to monochromatic visible light by image amplifier, scioptics by visual light imaging on digital camera, be transferred on computer by image pick-up card, then processed by image processing software, obtain corresponding detected image.
As shown in Figure 2, image amplifier is coupled to form through electrostatic lenses by intensifying screen and gleam image intensifier, and described intensifying screen is in order to increase the photon numbers of X ray, and described gleam image intensifier is in order to strengthen the photon luminance of X ray.X ray is mapped on intensifying screen, convert visible ray to, and photon numbers is increased, because the optical photon brightness after amplifying through intensifying screen is still very low, can further highlight by gleam image intensifier, in order to present image clearly on electrostatic lenses, the photoelectron image through strengthening focuses on electrostatic lenses, and electrostatic lenses is converted to the optical imagery more brighter than input to the photoelectron image focused on.Test shows, through gleam image intensifier, photon can double 10000 times, makes the picture after imaging more clear bright, and resolution is higher, has greatly improved picture quality.
Because X ray input face in the present invention is intensifying screen, compare traditional booster input screen, the imaging area of intensifying screen back photocathode is more much smaller than the photocathode of traditional booster input screen back, be that the imaging minification improves greatly, therefore, image amplifier in the present invention has larger visual field, can present picture detail more clearly.
Electrostatic lenses in the present invention can focus on and accelerate photoelectron, in order to export the electronic image that high-octane electron beam excitation goes out.Because intensifying screen is very low to the quantum efficiency of X ray, by faint visible images, excite the photocathode of intensifying screen back to produce the photoelectron of corresponding density, via electrostatic lenses, can make electronic image convert the visible images that size is dwindled to.
X ray in the present invention is penetrated by the high-frequency X-ray source, can obtain the x-ray that energy efficiency is higher, to accelerate image taking speed.
In the present invention, lens adopt the LED optical lens, can increase optical reflection, reduce light loss, improve light efficiency, further to improve image taking speed.
In the present invention, X ray is mapped on intensifying screen, converts the visible ray that wavelength is 540nm to, and the visible ray of 540nm wave band is green, easily is identified by the human eye and accepts.
In the present invention digital camera be CCD the CMOS camera, CCD CMOS can make visible images convert digital picture to, conveniently carry out post processing of image, make image meet observe needs.
Total the above, the image amplifier that high sensitivity image catenary system provided by the invention utilization is combined into as the sensitizing device by intensifying screen and low-light, can make that the visual field scope is large, image taking speed is fast, improve imaging sensitivity, can obtain the high quality image clear, that resolution is high.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can, in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on description, must determine technical scope according to the claim scope.
