In this study, a Compton camera combining a silicon pixel sensor and a scintillator was developed to improve the performance of a Compton-PET camera capable of simultaneous imaging of PET and SPECT radionuclides. Measurements using a sealed ⁵⁷Co source were conducted, and image reconstruction was performed using the ML-EM method. As a result, imaging was successfully demonstrated. The resulting angular resolution measure (ARM) was 18.2° (FWHM). Future work will focus on improving data analysis methods and integrating PET imaging to further enhance system performance.
