摘要： Embodiment of the present invention provides a method for generating a quality degradation model of an imaging system with a hardware imperfection. The method comprises the steps of obtaining a first image from a first simulation of the imaging system without the hardware imperfection, obtaining a second image from a second simulation of the imaging system with the hardware imperfection, and generating the quality degradation model learnt with a mapping function from an input degraded image measured from the imaging system to an output corrected image based on a plurality of input and out image pairs. The input image in each image pair comprises the second image, and the output image in each image pair comprises the first image. The quality degradation from the output image to the input image in each image pair characterizes a type of quality degradation specific to the hardware imperfection.
