Caprio, Jr. %T Collimator Selection for Ga-67 Imaging with the Anger Camera %D 1978 %J Journal of Nuclear Medicine Technology %P 205-206 %V 6 %N 4 %X Gallium-67 images have generally suffered from poor quality because of difficulty in properly collimating the multiple photopeaks released by the radionuclide. A comparison of the spatial resolution and septal penetration characteristics of two collimators we currently use for Ga-67 imaging—with a scintillation camera system equipped with single photopeak analyzers—is presented. Results show that the camera performs best when a medium energy collimator is used with the system’s photopeak analyzer centered around the 93-keV photopeak of Ga-67. %U https://tech.snmjournals.org/content/jnmt/6/4/205.full.pdf
