摘要	Photon Counting Detector (PCD) of a photon counting CT (PCCT) can directly measure each x-ray photon energy, enabling the material decomposition and tissue differentiation. Compared to the detector domain material decomposition, the imaging domain material decomposition is compatible with the traditional CT imaging reconstruction frame work and has much better computing efficiency, while it could amplifier the noise and suffers from beam hardness effects. In this paper, we propose a new algorithm fully utilizing the spectral information of photon counting detectors to effectively resolve beam hardening artifacts.
