Electron-tracking Compton camera imaging of technetium-95m

Imaging was conducted using an electron tracking-Compton camera (ETCC), which measures γ-rays with energies in the range of 200–900 keV from (95m)Tc. (95m)Tc was produced by the (95)Mo(p, n)(95m)Tc reaction on a (95)Mo-enriched target. A method for recycling (95)Mo-enriched molybdenum trioxide was e...

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