Conventional nuclear medicine, such as PET (Positron Emission Tomography) and SPECT (Single Photon Emission CT) has limited spatial resolution and sensitivity.
We propose a new imaging method utilizing multi-photons with time and spatial correlation.
We aim to develop a new imaging technology with high resolution, high sensitivity and high signal-to-noise ratio using angular sensitive detectors.
Reconstructed image comparison between double-photon (DPECT) and single photon method.
Comparison of SPECT/PET/DPECT principles
