Abstract
Imaging methods, imaging apparatuses and image processing devices are provided. In one aspect, an imaging method includes: scanning a subject to obtain a photon-counting sequence output by a photon-counting detector of a photon-counting CT system; determining, by using a photon-counting model and the photon-counting sequence, a target material distribution parameter value of the subject, and performing imaging based on the target material distribution parameter value. The photon-counting model is created by at least one of a charge sharing model, an energy resolution model, or a pulse pileup model. The charge sharing model is configured to eliminate energy spectrum distortion and counting loss caused by charge sharing. The energy resolution model is configured to eliminate energy spectrum distortion and counting loss caused by energy resolution. The pulse pileup model is configured to eliminate energy spectrum distortion and counting loss caused by pulse pileup.
