Abstract (in Japanese) (See Japanese page) 
(in English) A Bayesian approach to de-noise tissue time activity curves (tTAC) is proposed. The proposed method estimate the posterior distribution of the tTAC. A set of noise-free tTAC is simulated based on a compartment model for obtaining the prior distribution of the tTAC, and is used for the computatation of the posterior distribution. We evaluated the performance of the given rate constant as a prior information introduced when obtaining the prior distribution of tTAC by using simulated and clinical PET data.
