- W2352851260 abstract "The intensity gradient due to noise elements may compete with or even exceed that in the images in the research of photon-limited maximum likelihood expectation maximization(MLEM) based positron emission tomography/computed tomography(PET/CT) image reconstruction.An average median non-local means(AMNLM)method was developed to decrease the interference of the noise elements during image processing.The AMNLM method is based on the traditional image denoising method of the median non-local means filter,incorporating with anatomical side information.The method was used to analyze the clinical pulmonary disease PET/CT images.The parameters obtained from experiments show that the AMNLM method outperforms the anisotropic-median diffusion filtering(AMDF) and non-local means(NLM)in terms of visual assessment and trade-off between lesion contrast and noise,which shows the validity of this method." @default.
