- W4362239034 abstract "The attenuation of X-ray in matter is related to photon energy and material property. The traditional CT imaging technology adopts charge integrating detector, which cannot effectively utilize the photon energy information in imaging. With the ability to distinguish the photon energy, photon counting detector can improve the image quality if appropriate energy weights are chosen according to the attenuation change of matter under different X-ray energies. This paper focuses on the energy weighting imaging method based on the photon counting detector CT. In this paper, various kinds of materials are selected to explore the image-based energy weighting. Imaging experiments show that the energy weighting method can obtain higher contrast-to-noise ratio (CNR) than the conventional photon counting imaging and charge integrating imaging." @default.
