Scanning system is controlled by system control position, when opening work, radiographic source launches X-ray or high-velocity particles flow through it is detected to
Object is examined, is impinged upon on the digital detector of analyte detection position to be checked, the signal received is converted into image digitization by detector
Signal, then transfer signals in control system, control system is equipped with dedicated CT scan imaging software, carries out tomography to image and sweeps
It retouches, after scanning one is fixed-circumference, system image reconstruction is carried out by computer, forms tomoscan picture and threedimensional model,
The integrated treatments such as internal flaw judgement and storage are carried out again.Control centre of the control system as intelligent checking system, using
There is the model XRC-MCC type system control position of the design control mode of automation, to have forming technique.
Specifically, by existing general industry CT detection device install the application for ray non-destructive testing
Micromatic setting is finely adjusted the position of object to be checked by being mounted on the turntable of detection system using this micromatic setting,
It is in the detection position of object to be checked as far as possible around the center of detection ray, to be conducive to the projection and reconstruction in CT system
Process needs to meet rotation center, detector center, ray source focus three point-blank and perpendicular to detector
Condition, and it is quickly obtained best geometry amplification ratio, the detection accuracy of CT examination system is improved, it can also be by adjusting determinand
Position is so as to detecting multiple test points to be measured.Simultaneously as not being by directly adjusting the rotation in detection system
Turning platform, the system rotation center of avoiding is not in ideal position, so that actual control system center deviation ideal rotation center, i.e.,
Practical rotation center and reconstruction rotation center deviate, and not only deform reconstruction image, but also output dotted line edge etc.；In addition, this reality
The ray applied is X-ray, and operator can carry out control operation to micromatic setting outside sensing chamber, does not need to adjust object to be checked and exists
Position on CT equipment turntable makes the detection position of object to be checked be in detection ray as far as possible to carry out position adjustment to object to be checked
Center range, it is ensured that operator guarantees operator's personal safety far from ray, while improving detection efficiency.
