Abstract

L'acquisition de données par tomographie calculées par transmission et émission est réalisée avec le même analyseur. Les séries de données de transmission et d'émission étant spatialement enregistrées, la carte des coefficients d'attenuation décrite par les images de transmission restructurée peut être utilisée pour la genération d'une matrice mathématiquement précise pour la correction de données d'imagerie. Les dispositifs imageurs peuvent être caméras gamma (4).
