The check system comprises a radiation source for emitting radial, a detector for receiving the radial, a detecting zone for placing checked objects and a moving device for enabling the radiation source and the detector to move around the detecting zone. According to the check system, common dead zones such as two sides of the human body, two sides of hands and two sides of legs can be thoroughly eliminated without motions of changing gestures such as turning of an object human body, so that ineffective time of whole detecting can be reduced to the maximum degree, and passing rates of detected people can be improved; and meanwhile, a psychological feeling of being controlled of the detected people caused by changing the gestures can be greatly improved, and psychological discomfort and conflicted emotions of the detected people can be reduced.
Description
Technical field
This utility model relates to a kind of check system, especially for the check system of human body.
Background technology
Back scattering detects in imaging applications, ray becomes ray pen bundle point by point scanning object through the modulation collimation, simultaneously detector receives the ray that on object, scattering is returned, and during date processing, scanning position and signaling point point correspondence can be obtained reflecting the backscatter images of object information.
Usually the scan pattern that adopts is: ray pen bundle is tieed up scanning direction through the modulation collimation first; Ray pen bundle plane is along with detector is tieed up direction and human body relative translation along second together; The first dimension direction is substantially vertical with the second dimension direction.
Two kinds of methods are typically arranged: a kind of is that ray pen bundle scans in the horizontal direction, the vertically translation of ray pen bundle plane; Another kind is that ray pen bundle scans in the vertical direction, the plane along continuous straight runs translation of ray pen bundle.
The shortcoming of this scan pattern is the image that single pass detects a health of close detector that can only obtain the examinee, and the another side health is the blind area, can't scan; Want dead zone-eliminating, obtain complete human body image, the examinee must turn round 180 ° after single pass is completed scans for the second time, namely needs twice sweep to detect; Touch turn can increase invalid detection time, reduces on the whole and detects percent of pass.For example single-sweep typical case's time is about 10 seconds, and from the operator notify the examinee can turn round actual turn round and again pose stand firm time-consumingly usually at 1.5 seconds to 2 seconds, the operator confirms that the examinee has stood firm and need spend about 0.5 second to 1 second in addition; Just accounted for 20% to 30% invalid like this detection time; If being slow in action or exchanging slow meeting, the examinee causes more ineffective time.
Even another shortcoming of this scan pattern is to have carried out the twice sweep detection, but because scanning beam face and detector are traveling priorities, make and always have the surface parallel with the scanning beam face on human body, to beginning to can not clearly being scanned eventually, still there is the scan blind spot of fraction, such as the both sides of the chest of human body, the positions such as the left and right sides of lower limb.

According to one side of the present utility model, described radiographic source comprises a plurality of target spots of arranging in vertical direction, can be perhaps distributed x-ray source.
According to one side of the present utility model, described mobile device comprises guide rail, and described radiographic source and detector move along described guide rail.
According to one side of the present utility model, described guide rail is circular or oval-shaped.
According to one side of the present utility model, described guide rail is closed hoop.
According to one side of the present utility model, described radiographic source and detector form as one.
According to one side of the present utility model, this utility model provides a kind of inspection method, and described inspection method comprises the steps: inspected object is placed in detection zone; Radiographic source and detector are moved around detection zone, make simultaneously radiographic source send ray, and receive ray from the checked property volume scattering with detector.
According to one side of the present utility model, described radiographic source sends be used to the ray pen bundle that scans, and described mobile device makes described radiographic source and detector move around detection zone.
According to embodiment of the present utility model, adopted the motion scan path of arc, common scan blind spot and---such as health both sides, hands lower limb both sides etc.---can thoroughly have been eliminated by method of the present utility model.In addition, need not target body make and the action that changes attitude such as turn round, this can farthest reduce the ineffective time of whole detection, improves the personnel's percent of pass that detects; Also can greatly improve simultaneously the psychological feeling of being controlled of detected personnel that causes due to the change attitude and be subjected to, reduce its Psychological inadaptability and resentment.
Moreover, target spot with distributed x-ray source switches the Mechanical Moving that has replaced traditional flying-spot scanner direction, target spot switches only needs in addition that the control signal of specific time sequence can realize, has greatly simplified motor-driven complex mechanical structure, and scanning speed is easy to control.
Description of drawings
Fig. 1 is the schematic diagram according to the check system of embodiment of the present utility model.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, this utility model is described further.
As shown in Figure 1, the check system 10 according to embodiment of the present utility model comprises: the radiographic source 1 that is used for sending ray; Be used for receiving the detector 2 of ray; Be used for placing inspected object 5 detection zone 6 of (for example, being used for standing the examinee); For the mobile device 12 that radiographic source 1 and detector 2 are moved around detection zone 6, and for the control assembly 4 that system is controlled.Radiographic source and detector can form as one.Check system 10 can be the human body check system of radial imaging.
Mobile device 12 can make radiographic source 1 and detector 2 rotate around detection zone 6.For example, mobile device roughly rotates radiographic source and detector integratedly around vertical axis around detection zone.Mobile device 12 can be any suitable mobile device, just can realize the purpose of this utility model as long as radiographic source 1 and detector 2 are rotated around detection zone 6.
As shown in Figure 1, x-ray source 1 can be distributed source, and for example the CNT x-ray source, can have a plurality of outgoing target spots 101, and for example, radiographic source 1 can comprise a plurality of target spots 101 of arranging in vertical direction.The quantity of target spot is restriction not, and the quantity that accompanying drawing is painted only is used for signal, does not represent actually to be confined to this.Each target spot has the ability of independent emergent ray, and can be controlled according to the independent emergent ray of specific order by external control signal.In one embodiment, x-ray source 1 can be the stack of a plurality of x-ray sources, for example commonly causes X-ray tube, or other suitable isotope radiographic sources, such as gamma-ray source etc.
Detector 2 can change into the signal of telecommunication by absorption of x-rays, and further converts the digital signal that can be used for Computer display to.X-ray source 1 and detector 2 can be fixed by connecting rod and screw, keep relative position constant when mobile.In one embodiment, detector 2 is plastic scintillator detector or quasiconductor scintillator detector.
