Abstract

Due to the limited resolution and accuracy of several technologies that are able to get a digital X-ray image with a good performance in the very high rates, micro-pattern technology can achieve these features by using the most effective example of which is gas electron multiplier (GEM). The main objective of this project is to develop a two dimensions imaging that can be used in medical imaging purposes. The project consists of the theoretical parts of the process, including simulating the best detector dimensions, geometry, and the energy range of the applied radiation. Furthermore, constructing a large active area of triple GEM detector, and preparing the necessary setup parts for medical imaging system assumed. This paper presents the designing and construction of a prototype of triple-GEM detector (10cm x10 cm) that can achieve the goals as a first step toward attaining this project. In addition, the preliminary results from X-ray and some gamma sources as a testing of the prototype detector will be presented, added to that the discussions of outlined tasks and achievements. This paper will show the future plane of the whole project and more details about the next stages.
