Title: High Resolution Radionuclide Imaging Using Focusing Gamma-Ray Optics

Conference ·

Significant effort is being devoted to the development of noninvasive imaging systems that allow in vivo assessment of biological and biomolecular interactions in mice and other small animals. Although single-photon emission tomography (SPECT) and positron emission tomography (PET) are well-matched to the study of physiological function in small animals, the spatial resolutions of 1-2 mm currently achievable with these techniques limits the types of research possible. For this reason, we are developing a small animal radionuclide imaging system using grazing incidence optics to focus the low-energy gamma-rays emitted by {sup 125}I, {sup 95m}Tc, {sup 96}Tc, and {sup 99m}Tc. We compare this approach to the more traditional use of absorptive collimation.
