Imaging was conducted using an electron tracking-Compton camera (ETCC), which measures y-rays with energies in the range of 200-900 keV from Tc-95m. Tc-95m was produced by the Mo-95 (p, n) Tc-95m reaction on a Mo-95-enriched target. A method for recycling( 95)Mo-enriched molybdenum trioxide was employed, and the recycled yield of Mo-95 was 70%-90%. Images were obtained with the gate of three energies. The results showed that the spatial resolution increases with increasing y-ray energy, and suggested that the ETCC with high-energy y-ray emitters such as Tc-95m is useful for the medical imaging of deep tissue and organs in the human body.
