Multi-tracer imaging can provide important information for diagnosis of diseases and research in fields such as medicine and life science. Single photon emission computed tomography (SPECT) is one of nuclear medicine imaging methods, and SPECT can visualize multi-nuclide. In this study, we performed simultaneous ¹¹¹In and ¹⁷⁷Lu imaging with double photon emission coincidence method to reduce background and distinguish nuclides by using parallel hole collimators and GAGG detectors.
