MRI based Bayesian image reconstruction methods for positron emission tomography reconstruction with the aim at improving image quality was developed. The line site map from MRI as a priori is made up of either a modified Markov random field or Canny

We propose an image feature extraction method based on the thermal theory for high noise PET images. The PET imaging, which records physiological activities of tissues, is broadly used to provide diagnostic information for investigating clinical diso

To improve the high noise problem for a PET image is important work because the quality of the PET image and the diagnosis accuracy is affected by this noise. For this reason, a novel subband denoising technique is provided. The method is based on su

Image contrast is frequently affected by the high radioactivity uptakes of source organs such as bladder and GI track in [F-18]FDG PET studies. Certain important tumors neighboring to these organs are potentially mis-diagnosed. The study is to propos

Since the positron emission tomographic (PET) image shows the abnormal activity of brain by the different parts of the brain respond to different stimuli and the patient's response to noise, illumination, change in mental concentration, and other act

In generally, the dynamic positron emission tomographic image (PET) that imaging with FDOPA plays as a powerful functional image tool to clinical diagnosis for the tissue disorders of Parkinson's disease. However, high noise is always shown in dynami
