| Abstract(in English) | In parametric image reconstruction using dynamic PET data, the method using the histogram data of each time flame influences the estimated accuracy of parametric image because the time information cannot be effectively used by the method. In this paper, the method which is estimated accurate time activity curve of radioactivity (TAC) by using the list mode data. Using the method, it is expected to estimate a highly accurate parametric image. Simulation results show that the proposed method produces higher estimated TAC than the conventional method. |
