Abstract

Imaging of 95mTc radioisotope was conducted using an electron tracking-Compton camera (ETCC). 95mTc emits 204, 582, and 835 keV gamma rays, and was produced in the 95Mo(p,n)95mTc reaction with a 95Mo-enriched target. The recycling of the 95Mo-enriched molybdenum trioxide was investigated, and the recycled yield of 95Mo was achieved to be 70% - 90%. The images were obtained with each of the three gamma rays. Results showed that the spatial resolution increases with increasing gamma-ray energy, and suggested that the ETCC with high-energy gamma-ray emitters such as 95mTc is useful for the medical imaging of deep tissue and organs in the human body.
