Tc γ-ray sources showcases the high sensitivity of 0.13%~0.21% cps/Bq. Phantom imaging distinctly delineates individual column sources spaced 7 mm apart, indicative of an impressive spatial resolution of 3.2 mm. These findings lay the groundwork for integrating perovskite detectors into nuclear medicine γ-ray imaging systems, offering a balance of cost-effectiveness and superior performance.
