Abstract

The clinical application of dual-energy CT (DECT) system is a significant technical progress in X-ray medical imaging for recent years. Compared with conventional CT, DECT is capable of differentiating tissue and eliminating beam hardening artifacts and plays a unique role in current diagnostic imaging. But it is not easy for the researchers to acquire DECT raw projection data. And it has become a bottleneck for those theoretical explorations on DECT imaging. We propose a method to implement the numerical simulation for the material decomposition and image reconstruction of DECT imaging, based on the physics and mathematics of CT/DECT imaging. The experimental results show the validity and the reliability of our method.
