Abstract


High-performance computing capability enabled the development of a multi-energy X-ray imaging system which includes a data-acquisition, pre-processing and transmission module, followed by image reconstruction module. The data acquisition, pre-processing and transmission module are located at the pixel sensor side, and the image reconstruction is completed by using a GPGPU on a host PC. Thus, it requires a high-speed communication channel between the sensor side and the host PC. In this paper, we introduce our prototype multi-energy X-ray system focusing on the data acquisition, pre-processing, and transmission module. The experimental results demonstrate the feasibility of our proposal to the single photon counting X-ray system.
