We are conducting research and development of collimatorless imaging technology as a new nuclear medicine imaging technique. For collimatorless imaging, we are investigating an imaging technique that combines magnetic field and RI. The Larmor precession induced by the application of a magnetic field to a nucleus is detected by the oscillation of the angular correlation of cascade gamma-rays. It is known that the frequency of the oscillation is proportional to the applied magnetic field strength. In this study, we utilize the two-photon emitting nuclide clinically used in SPECT, and measure it by changing the position of the applied static magnetic field to determine the presence or absence of the source at the applied position, and to quantify the imaging method.
