In Nuclear Medicine, PET (Positron Emission Tomography) is important imaging method to detect cancers in early stage or whole body molecular imaging, however, PET suffers from the degradation of spatial resolution caused by positron emitter and the use of PET is limited to positron emitting nuclides. New types of multi nuclide and multi molecule imaging with high signal to background ratio is required. Our group are developing a novel nuclear medicine imaging method called DPECT (Double Photon Emission CT) or MPECT (Multi Photon Emission CT) utilizing multi photon emitting nuclides. The coincidence detection of multi-photons will improve the signal to background ratio greatly compared with the existing gamma-ray imaging method, such as Compton imaging. In this research new imaging method with several technologies is being developed using mulit-photon, electron tracking to localize the position of molecules in clearer way.
