Description
Nuclear medical imaging devices, PET and SPECT, are powerful and highly sensitive to the accumulation of molecules with a small amount of radio-nuclides. Extracting physico-chemical micro-environmental information in addition to accumulation could contribute to more accurate diagnosis and therapy in radio-theranosics. A novel direct imaging technique of three gamma decays from ortho-positronium together with two gamma decays for quantifying the 3g/2g ratio indicating oxygen concentration and void size in PET device, as well as the cascade gamma-ray sensing of pH with In-111 nuclides in SPECT device will be discussed in the presentation.
