In current PET, only a few percent of gamma rays emitted from a patient are used for imaging. Therefore, improvement of the sensitivity is a hot topic worldwide. Axial extension, which is referred as total-body PET, is essential in terms of the sensitivity improvement. In organ dedicated imaging, on the other hand, it is possible to improve the sensitivity without increasing the number of...
Multi-isotope imaging is important for investigating multi-molecule dynamics in individuals. PET and SPECT dual tracer imaging in vivo is demonstrated with a developed Compton PET hybrid camera. In nuclear medicine imaging, quantum chemical sensing, such as pH and chemical state of molecule, can be additional value to accumulation imaging. pH sensing and imaging is demonstrated with liquid...
The spectroscopic investigation of nuclei at high spin states has led to many discoveries, e.g., exotic shapes, super-deformation, shape coexistence, and chiral symmetry. In this endeavor, the accurate spin-parity assignment to nuclear states is crucial. Many studies in the literature have focused on finding the directional correlation ratios (DCO) for the assigning spins without any...
