Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention;
Fig. 2 is image acquisition process flow diagram of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
With reference to Fig. 1, this embodiment is by the following technical solutions: energy-conservation X digital imaging device, it comprises x-ray source 1, with the collimating apparatus 3 of adjustable slit, clamping device 4, intensifying screen 5, support glass 6, gear train 7, stepper motor 8, line array CCD 9 and camera bellows casing 10, x-ray source 1 side is disposed with the collimating apparatus 3 with adjustable slit, clamping device 4 and intensifying screen 5, intensifying screen 5 is arranged in support glass 6, support glass 6 is arranged on camera bellows casing 10, camera bellows casing 10 side is provided with stepper motor 8, stepper motor 8 is connected with gear train 7, gear train 7 is connected with clamping device 4, line array CCD 9 is arranged on camera bellows casing 10, accumulator is provided with in described stepper motor 8, described stepper motor 8 is wrapped with sun power and receives shell, described accumulator receives shell by wire and sun power and is connected.
It should be noted that described x-ray source 1 is also connected with high voltage control cabinet 2.
It should be noted that described line array CCD 9 is also connected with image acquisition analytic system 11.
It should be noted that described support glass 6 is tempered glass.
It should be noted that described camera bellows casing 10 is made up of skin, internal layer and cavity layer.
It should be noted that described cavity layer is light heat insulation layer.
This embodiment takes the mode of object movement, and namely camera is motionless, and is photographed thing relative to line array CCD and moves, and reaches the effect of scanning.This scan mode makes system architecture fairly simple, and the Collimation Ratio of X ray is more convenient, because if with camera scanning, the X-ray beam of collimation must synchronous scanning, and also namely x-ray source wants synchronous scanning, makes scan-synchronized mechanism greatly complicated like this.During work, rotary anode tungsten target silver filtrator x ray generator sends X ray, projects on intensifying screen after collimating device collimation after being photographed thing.Meanwhile, stepper motor drives clamping device 4 to make the relative CCD motion of article, and TDI line array CCD starts to gather image.As long as the movement velocity of the line frequency of CCD and scanning mechanism matches, the image not having to distort just can be collected
This embodiment gathers image flow process: with reference to Fig. 2, first will judge scanning mechanism whether in starting point, if do not exist, just give an order and scanning mechanism is returned; Next determines whether signal, and this ensures that CCD can collect key one step of useful data.Because radiographic source used exposure can not accomplish that computing machine controls, necessary Non-follow control, if can not ensure CCD collection and x-ray source emerging ray synchronously, then can not obtain correct image.Threshold decision method is adopted to ensure that and correctly can obtain image.Adopt in program to follow to gather and judge, when cycling time exceed certain hour (being generally set as 10s) there is no a signal time, exit collection.If CCD collects signal, then exit circulation, formally gather image.Be start x-ray source again, take pictures.During cycle criterion, manually boot x-ray source, if all are normal, CCD should collect signal, exits rapidly circulation (connect and gather band judgement, be no more than 10ms), starts scanning mechanism, carry out formal image acquisition.Judge that data are very short, so therefore make the increase of exposure dose be very little owing to gathering.The digital signal that EC11 line array CCD exports, is input to image pick-up card by cable, internal memory of directly making a gift to someone after capture card collection; Be finally exit image acquisition, close x-ray source, make scanning mechanism return initial point.Through above process, obtain a complete radioscopic image.By follow-up operation, can by Image Saving in the storage medium such as hard disk, CDR.
This embodiment adopts thin beam X-ray imaging, inhibit scattering on the impact of imaging, reducing the x-ray dose needed for imaging when meeting picture quality from system architecture.
