X光高分辨探测层析成象技术的研究

The study work of this project was carried out strictly according to the research content and working agenda of our project application. The roughly state of the research work being carried on is :.First, it is that we investigated on the state of the technology of Direct high-resolution tomography & image and especially technology of detector used in home and overseas by ways of literature making sure that our research work is based on a new and more advanced level; the second is that we chose the research scheme of X-ray High-resolution Tomography & Image detector ，that is, we took CsI（T1）scintilating screen to transfer the X-ray to visible light, using array CCD as optic-electrical detecting units, between the CsI（T1）scintilating screen and CCD unit，we used fiber and fiber optical plate（FOP）to carried out the task of coupling and transmission the ray, the third is that we carried out many experiments and tests on the X-ray High-resolution detection efficience and the last is that we made some ways to compensate and consummate the experiments according to problems encountered in the researching work.Our basic conclusion to the project though the research work is as follow:1、We made a breakthrough from the traditional or normal X-ray detector design scheme and our design is to be a important developing orientation of the X-ray High-resolution Tomography and Image detector in the future.2、The problem of loss in the procedure of transmission and coupling can be dissolved well by means of our detector realizing scheme using fiber optical panel (FOP) to couple and transmit the light and also the detecting efficiency and resolution is also kept high and realize our anticipation, it is a an ideal detecting scheme for present industry X-CT.3、With blocking and integration style, this new structure detector can offer necessary foundation and condition for x-ray Direct Detecting Tomography & Image technology of minimal system with low cost.
