Abstract
The invention discloses a digital X-ray flat panel detector comprising a scintillation screen and an amorphous silicon sensor array closely attached to the scintillation screen. The scintillation screen comprises a substrate, a reflection layer attached to the upper surface of the substrate, a scintillation layer deposited on the reflection layer and a waterproof thin film layer laminated on the scintillation layer, wherein the scintillation layer is an acicular-structure cesium iodide crystal array, and the thickness of the scintillation layer is 800-1000 [mu]m. The amorphous silicon sensor array is arranged on the lower surface of the substrate. With the above method, the digital X-ray flat panel detector adopts the high-resolution cesium iodide scintillation screen, and has good imaging performance.
Description
Technical field
The present invention relates to X radial imaging technical field, particularly relate to a kind of digital X-ray flat panel detector.
Background technology
The imaging performance of digital X-ray flat panel detector depends primarily on the image resolution ratio height of scintillation screen, scintillator in scintillation screen is generally used cesium iodide crystal now, but cesium iodide material is hygroscopic materials, when it absorbs airborne moisture and during deliquescence, can affect the characteristic of scintillator, particularly image resolution ratio reduces greatly, therefore, effectively encapsulation scintillator, prevent that scintillator from making moist, improve the image resolution ratio of scintillation screen, thereby can improve the imaging performance of digital X-ray flat panel detector.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of digital X-ray flat panel detector, adopts and has high-resolution cesium iodide scintillation screen, has the advantages that imaging performance is good.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of digital X-ray flat panel detector is provided, comprise: scintillation screen and the amorphous silicon sensor array of being close to described scintillation screen, described scintillation screen comprises: substrate, be attached to described upper surface of base plate reflector, be deposited on flash layer on described reflector, be pressed together on the waterproofing membrane layer on described flash layer, described flash layer is the cesium iodide crystal display of acicular texture, its thickness is 800-1000 μ m, and described amorphous silicon transducer display is positioned at the lower surface of described substrate.
In a preferred embodiment of the present invention, described substrate is glass or glass mat.
In a preferred embodiment of the present invention, described reflector is metallic film.
In a preferred embodiment of the present invention, described metallic film is aluminium film or silverskin.
The invention has the beneficial effects as follows: digital X-ray flat panel detector of the present invention, X ray is transformed into visible ray by cesium iodide scintillation screen handle; Visible ray is transformed into signal charge by amorphous silicon transducer display and obtains image; Because this cesium iodide scintillation screen has the characteristic of image high-resolution, therefore use the digital X-ray flat panel detector of this scintillation screen to have the advantages that imaging performance is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of X ray flat panel detector one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, scintillation screen, 2, amorphous silicon transducer display, 10, substrate, 11, reflector, 12, flash layer, 13, waterproofing membrane layer.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of digital X-ray flat panel detector, comprise: scintillation screen 1 and the amorphous silicon sensor array 2 of being close to described scintillation screen 1, described scintillation screen 1 comprises: substrate 10, be attached to described substrate 10 upper surfaces reflector 11, be deposited on flash layer 12 on described reflector 11, be pressed together on the waterproofing membrane layer 13 on described flash layer 12; Described amorphous silicon transducer display 2 is positioned at the lower surface of described substrate 10, for visible ray is transformed into signal charge, obtains figure.
Wherein, described substrate 10 is glass or glass mat, smooth surface, to X ray absorptivity lower than 5%; Described reflector 11 is metallic film, and described metallic film is preferably aluminium film or silverskin, and its reflectivity to visible ray is greater than 90%, can improve image resolution ratio; The cesium iodide crystal display that described flash layer 12 is acicular texture, for X ray is transformed into visible ray, its thickness is 800-1000 μ m, the efficiency that absorbs sigmatron is high, can improve image resolution ratio; On described flash layer 12, also pressing has waterproofing membrane layer 13, can prevent that the cesium iodide crystal in flash layer 12 from absorbing airborne steam, thereby effectively improves the performance of flash layer 12 and extend its useful life.
The present invention has disclosed a kind of digital X-ray flat panel detector, and X ray is transformed into visible ray by cesium iodide scintillation screen handle; Visible ray is transformed into signal charge by amorphous silicon transducer display and obtains image; Because this cesium iodide scintillation screen has the characteristic of image high-resolution, therefore use the digital X-ray flat panel detector of this scintillation screen to have the advantages that imaging performance is good
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
