Abstract
The invention provides an X-ray image capturing device. The X-ray image capturing device has the main advantages that a fiber optical scintillation plate which is used as a first scintillator and a second scintillator of a columnar thin film formed by cesium iodide are combined with one another and are applied to the X-ray image capturing device, most of X-rays can be converted into first visible light after the X-rays are transmitted into the X-ray image capturing device via the second scintillator, the X-rays which are not absorbed by the second scintillator are further transmitted into the first scintillator and are converted into second visible light under the effect of the first scintillator, the first visible light and the second visible light are ultimately transmitted into the surface of a sensor array under total-reflection effects of light guide channels of the first scintillator, accordingly, the X-rays which reach the surface of the sensor array can be reduced, the radiation lives of sensors can be prolonged, and random noise generated by the X-rays can be lowered; the second scintillator which is high in light yield as compared with the fiber optical scintillation plate which is used as the first scintillator is used as an initial incident plane for the X-rays, the partial X-rays which are not absorbed by the second scintillator can be absorbed in the first scintillator and can be converted into the corresponding visible light, accordingly, light output of detectors can be increased, and the sensitivity of the detectors can be improved.
Description
Technical field
The present invention relates to a kind of radiation detector technical field, more particularly to one kind is applied to X-ray flat panel detector
In radioscopic image capturing apparatus.
Background technology
With the development of medical technique level, X-ray flat panel detector popularity rate clinically is greatly improved.
The requirement of the image that clinician obtains to detector system is also more and more harsh.Flat panel detector substitutes former film cassette
Become major radiation with IP plate and check image-forming block.
And the image capture part as flat panel detector also has a lot of researchs, such as Chinese patent in industry in recent years
Document (CN 102934173A), american documentation literature (US 6635877B2) and american documentation literature (US 5554850) are all
There is the disclosure of this respect technology.
Specifically, Chinese patent literature (CN 102934173A) and american documentation literature (US 6635877B2) are all taken off
Revealed a kind of by cesium iodide (Cerium iodide；CsI) scintillator and fibre faceplate (Fiber Optical Plate；FOP)
The scintillator panel combining and being formed.Wherein, Chinese patent literature (CN 102934173A) is to disclose a kind of scintillator face
Plate, it passes through to grow cesium iodide (CsI) scintillator of column on aluminium base, then using both sides tape by cesium iodide scintillator
Back-off above forms this scintillator panel to fibre faceplate (FOP)；And american documentation literature (US 6635877B2) then discloses
Including the fibre faceplate (FOP) possessing through light, the scintillator being formed directly is deposited with this fibre faceplate, covers this scintillator
Ground floor Parylene film, on this ground floor Parylene film formed aluminium film and in this aluminium film formed the second layer group
The scintillator panel of Rayleigh film.
In both of the aforesaid patent document, the element directly participating in for X-ray being converted into visible ray all only has cesium iodide to flash
Device, fibre faceplate only acts as the effect of the light conduction pathway of visible ray, and the setting of the thickness of cesium iodide scintillator typically has
A range of, usually 400～600 μm, if thickness exceedes this value range although detector sensitivity can be improved,
But spatial resolution can decline on the contrary, therefore this value range be to equalize detector sensitivity and spatial resolution and
Set, but X-ray can not be completely converted into visible ray by the cesium iodide scintillator under this thickness, still have 10～30%
X-ray is not absorbed by cesium iodide scintillator it is clear that greatly reducing light output and the sensitivity of detector；Additionally, being converted into
The part of visible ray is to be conducted further by fibre faceplate, and fibre faceplate (FOP) is typically by core glass, light absorbs
Three kinds of materials such as glass and the skin glass as covering are according to certain proportioning clinkering, the folding of core glass therein
Penetrate the refractive index that rate is more than covering skin glass, due to total reflection, the only light beyond critical angle could transmit in a fiber,
So this scintillator panel that cesium iodide scintillator and fibre faceplate combine, inevitably reduce the output of light,
And then reduction detector sensitivity；Furthermore, unabsorbed X-ray reaches the sensor array surface of detector, can be to biography
Sensor causes radiation injury, and then reduces the detector life-span, meanwhile, also can inspire hole and electricity in the silicon substrate of detector
Son is right, and hole and electronics, to electric signal in the photodiode entering into detector, can be caused to strengthen, are shown as bright on image
Point, and random distribution, increased the noise of image, and this X-ray random noise is particularly evident for CMOS flat panel detector.
Additionally, another american documentation literature (US 5554850) is then directly to adopt flash fiber panel (Fiber
Optical Scintillation Plate；FOSP) as scintillator and transmission line, but due to flash fiber panel base
Volume density is low, be amorphous phase as the constituent core glass of flash fiber panel, it, as scintillator, is produced with X-ray
Raw interaction is limited, and with respect to the scintillator of cesium iodide material, light yield is less, thus detector sensitivity also will not
Too high.
Therefore it is necessary to a kind of radioscopic image capturing apparatus overcoming prior art disadvantages are proposed, to solve existing skill
In art with cesium iodide for scintillator insufficient to X-ray absorption, with flash fiber panel for scintillator light output limited, combine iodine
The problems such as light output of change caesium scintillator and fibre faceplate and sensitivity decrease.
