Abstract
The present invention discloses a method and the equipment thereof for the radiation imaging of a double-imaging scan with a single radiation source. In the method, two beams of X-rays are emitted by the single radiation source, and two scanning images are acquired by two sets of detector arrays and image acquiring systems connected with the detector arrays. The first set of the detector arrays acquires a front view scanning image which is mainly based on the image to reflect an object in a view, and the second set of the detector arrays is based on an auxiliary view to reflect a side view scanning image of the object. The present invention solves the problem that when the object is observed from a single view angle, the image of the object is caused to be superimposed, and the shape and the substance and the object can not be distinguished. Compared with the prior art, the present invention has the advantages of simple structure, low cost, high testing speed and convenience.
Description
Technical field
The present invention relates to the scanning radiation formation method and the device thereof of radiation detection system for large body, especially for scanning radiation formation method and the device thereof in the van container radiation checking system.
Background technology
The radiant image technology can be had an X-rayed the inside to object under the noncontact situation by means of the penetration capacity of sigmatron, thereby obtains the fluoroscopy images of object.In the prior art, inspection for large-sized object, the principle of work of scanning radiation imaging all adopts by radiation source emission X ray, X ray passes and converts electric signal input picture acquisition module to after testee is received by detector, by image collection module picture signal is imported graphoscope and shows institute's altimetric image.Generally speaking, the formed fluoroscopy images of radiant image is the projection of the total material that penetrated of ray line, if a plurality of objects are just in time placed along the direction of ray incident, be the image that forms along the stack of the whole objects of scanning beam flow path direction then, be unfavorable for like this checking being hidden in other object article behind at formed scan image.In order to address this problem, in the radiant image field, computed tomography is a kind of main body reconstruction technique of comparative maturity, but is to use the shortcoming of this technology to be: not only complexity coefficient is big, the cost height, and can't check apace large-sized object.
Summary of the invention
At the shortcoming that exists in the above-mentioned prior art, the purpose of this invention is to provide a kind of simple in structure, cost is low, check the method and the device thereof of the two image scanning radiant images of fireballing single radiation source.Use it convenient, convenient, can carry out detecting object than omnibearing multi-visual-angle.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes in the following way:
The two image scanning radiant image methods of single radiation source, it adopts by radiation source emission X ray; X ray passes and converts electric signal input picture acquisition module A to after tested container is received by detector A; By image collection module A picture signal is imported graphoscope A and show institute's altimetric image.Be characterized in, launch the X ray of another different angles at same radiation source, its ray is angled to be passed tested container and receives and convert to electric signal input picture acquisition module B by another detector B; By image collection module B picture signal is imported in the different windows of graphoscope B or same graphoscope A and shown institute's altimetric image simultaneously.
Realize the device of the two image scanning radiant image methods of single radiation source, it comprises radiation source, two detector arrays and the image-taking system that is connected with each detector array.Its design feature is to be equipped with two collimating slits on the collimating apparatus of described radiation source and to make X ray form the ray line of different angles.The X ray of the different angles that described two detector arrays limit over against the collimating slit by collimating apparatus respectively.
Method and device thereof that the present invention adopts, owing to adopted above-mentioned form, utilize same radiation source only to increase by one group of detector array and image-taking system, can form the main side-looking scan image that forms side-looking reflection object on scan image and another angle of facing of looking the reflection object.Two mutual mappings of scan image can true reflection shape and essence.Compare with prior art, realized identification the different depth object in mode cheaply.Use method of the present invention convenient, convenient, inspection speed is fast.Apparatus structure of the present invention is simple, cost is low.Can in existing fixed formula container check system, directly reequip, also can in newly-built fixed and portable van container detection system, use.
The invention will be further described below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Fig. 1 is the fundamental diagram of the inventive method;
Fig. 2 is a device schematic layout pattern of implementing the inventive method.
Embodiment
Referring to Fig. 1, the two image scanning radiant image methods of single radiation source, it adopts and launches the X ray of two different angles by radiation source 1.Each bar X-ray beam passes tested container and is received by detector A3 and detector B4 respectively, converts electric signal then to and imports corresponding image collection module A5 and image collection module B6 respectively.By image collection module A5 picture signal is imported graphoscope A7 and show institute's altimetric image.By image collection module B6 picture signal is imported in the different windows of graphoscope B8 or same graphoscope A7 and shown institute's altimetric image simultaneously.
Referring to Fig. 2, realize the device of the two image scanning radiant image methods of single radiation source.It comprises radiation source 1, two detector arrays 3 and 4 and the image-taking system that is connected with each detector array 3,4.Being equipped with two collimating slits on the collimating apparatus 2 of described radiation source 1 makes X ray form the ray line of different angles.The X ray of the different angles that detector array 3 and detector array 4 limit over against the collimating slit by collimating apparatus 2 respectively.The use of apparatus of the present invention, first group of detector array 3 connected image-taking system is the same with the conventional sweep check system, the scan image of facing as front view reflection object, second group of detector array 4 connected image-taking system are then accepted the scan image on another angle, as the side-looking scan image of auxiliary view reflection object.So just solved the subject image stack that single visual angle observation post causes and can't differentiate object true shape and essential problem.
Certainly, according to the design of the invention described above technical scheme, if the system that adopts a plurality of detectors of single radiation source and image collection module thereof to form.For example, be equipped with three above collimating slits and make X ray form the X ray line of different angles on the collimating apparatus of single radiation source, the detector array of using corresponding number is respectively over against each X ray line.All like this kind of formed technical schemes of form also should belong to protection scope of the present invention.
