| Outline of Final Research Achievements |
Positron emission tomography (PET) plays an important role in diagnostic imaging and molecular imaging researches. Its utility is supported by physical quality control of PET scanners, among which the most important is quantitative evaluation and calibration. However, with the conventional method using a phantom and a dose calibrator, its reliability and convenience were limited. In this research, we developed novel traceable point-like sources, evaluation and calibration protocols using them, promoting multicenter studies on a total of 13 models in Japan, and revealed the usefulness of the proposed method.
