Abstract

Structure ayant une résolution extrêmement élevée. Elle comprend un réseau de collimation 10 en un matériau relativement imperméable aux photos gamma présentant un grand nombre de canaux parallèles 30 définis par des parois, et de matériau scintillateur disposé dans les canaux, vers l'extrémité de ces derniers qui se trouve à l'opposé de la source de photons gamma.
