We are developing a Multi-photon gamma-ray coincidence imaging method using a cascade gamma-ray emission nuclide. The coincindence technique can provide a high signal to noise ratio and it provides a new possibility of angular resolving detectors and collimators. This presentation summarizes the overview of the technique.
