Brief description of the drawings
Fig. 1 is the structural representation of pencil-beam that one embodiment of the invention is provided low energy numeral borne densitometers high.
Fig. 2 is the another structural representation of pencil-beam that one embodiment of the invention is provided low energy numeral borne densitometers high.
Specific embodiment
In order that the technical problems to be solved by the invention, technical scheme and beneficial effect become more apparent, below tie
Drawings and Examples are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
It is used to explain the present invention, is not intended to limit the present invention.
It is the structural representation of the pencil-beam low energy numeral borne densitometers high that the present invention is provided referring to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2
Figure, the borne densitometers include suspension bracket 1, x-ray source 2, beam-defining clipper 3 and detection bed (4 and 5), and suspension bracket 1 is in inverted L-shaped, and x-ray source 2 is pacified
On the upper end floor beam of suspension bracket 1, beam-defining clipper 3 is assemblied in the underface of x-ray source 2, and detection bed (4 and 5) is arranged on beam-defining clipper 3
Lower section, detection bed (4 and 5) is just to beam-defining clipper 3 so that x-ray source 2 is limited through beam-defining clipper 3 when patient is lain in detection bed (4 and 5)
X-ray after beam is just radiated at patient's active component, in case influence is detected and produces unnecessary X-ray.The X of the present embodiment
Radiographic source 1 uses Polaroid technology, and detection time is greatly shortened, and through experiment test, detection time (exposure) is only 2 seconds.
Preferably, x-ray source 1 is by a tapered radiation of spot light, and because the light field required for detection is square
Or rectangle, therefore, beam-defining clipper of the invention 3 is bucket shape structure of the up-small and down-big and cross section in quadrangle, i.e. rectangular pyramid
Structure, and cross section is preferably square or rectangular.Pact of the X-ray that the spot light of so x-ray source sends in beam-defining clipper
A bucket shape light beam 8 in square is formed under beam, the forward direction of bucket shape light beam 8 is radiated in detection bed (4 and 5), just irradiates
At patient's effective detection position, the bucket shape light beam 8 of square can be formed to X-ray and will not produce unnecessary X-ray, and
And, this way of restraint can produce more preferable imaging effect, make picture quality higher, and it is more accurate to detect.Beam-defining clipper 3 is lead system
Beam-defining clipper, with preferable beam light and protective action.
Further, detection bed (4 and 5) of the present embodiment includes bed body 4 and bed surface 5, and slide rail 7 is provided with bed body 4,
Bed surface 5 is slidably installed by slide rail 7 in bed body 4, and the thread (broken line representation in figure) that bed surface 5 is slided in bed body 4 is preferably
Less than 50cm, i.e., bed body 50cm is skidded off forward, it is also 50cm to slide rearwardly out bed body.Certain above-mentioned distance is used only for explaining bed surface
Slip in bed body is limited with particular thread, and is not used to limit thread size, specifically can be according to actual conditions
It is fixed.
Preferably, the digital photoelectronic imaging plate 6 for digital imagery, numeral are installed in bed body 4 and positioned at the lower section of bed surface 5
The bucket shape light beam that photoelectronic imaging plate 6 is just being sent to x-ray source 2, it is converted to digital electric signal as by sightless X-ray
Device, it is high with sensitivity, disturb small, image clearly, the features such as x-ray dose used is small, X-ray is sent in x-ray source 2
Afterwards, digital photoelectronic imaging plate 6 can be imaged in time, greatly shorten imaging time, and then reduce sweep time, and the figure being imaged
As being of high quality.
In sum, the pencil-beam low energy numeral borne densitometers high that the present invention that the present invention is provided is provided use pencil-beam one
Secondary imaging technique, is greatly reduced the review time (exposure), with preferably beam light effect, it is to avoid patient receives extra ray
Radiation, and opto-electronic conversion component used high conversion efficiency so that the precision of images is higher, lifted clinical detection precision, tool
There is wide development potentiality.
It should be appreciated that application of the invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or converted, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
