Design technique based on CDD function for industrial CT system

  • Industrial computed tomography(ICT) is an advanced, non-contact and non-destructive testing method. It is complicated, non-universal and expe ns ive. It is necessary to make the custom development to reduce the risk and the c ost. A kind of design technique frame based on the contrast-detail-dose(CDD) fu nction was proposed for the development of ICT system. According to this frame, t he design method for fan-beam 3rd generation two dimensional ICT(2D-ICT) was d ed uced and the corresponding software platform was implemented which is consisted of three parts. They are the computer aided design(CAD) part based on the CDD func tion, the simulation part and the performance evaluation part. The initial desig n parameters firstly entered the CAD part. They secondly entered the simulation part if they passed the CAD check. The simulation results were finally evaluated by the evaluation part. The validity of the proposed method was proved by the computer simulation and the example of the engineering development.
