| Abstract(in English) | The accuracy of the estimated parametric images is largely dependent on that of the tissue time activity curves (tTACs.) Though the spatio-temporal PET reconstruction methods have been studied, these methods have not produced the tTACs with high accuracy enough, and it takes much time to calculate with the methods. To solve these problems, we have developed a spatio-temporal reconstruction method based on the dynamic row-action maximum likelihood algorithm (DRAMA,) which requires a few iteration counts and achieves high accuracy as a spatial reconstruction. In this study, we show the validation of the proposed method for small animal dynamic PET data. |
