Title
(EN) APPARATUS AND METHOD FOR DETECTING GAMMA RAY RADIATION
(FR) Appareillage et méthode de détection de rayons gamma
Abstract
(EN)
An apparatus for detecting gamma ray (GR) radiation having a plurality of detector cells arranged in an array is disclosed. Each cell includes a housing having an aperture, the housing comprising a GR absorbing material, and a GR detector disposed within the housing such that external gamma rays are received at the GR detector via the aperture. The apertures of each cell are aligned.
(FR)
L'invention concerne un appareillage de détection des rayonnements gamma (GR) possédant une pluralité de cellules détectrices disposées en réseau. Chaque cellule comprend un boîtier muni d'une ouverture, le boîtier comprenant un matériau absorbant les rayons gamma, et un détecteur de rayons gamma disposé dans le boîtier de telle sorte que les rayons gamma extérieurs atteignent le détecteur de rayons gamma via l'ouverture. Les ouvertures de toutes les cellules sont alignées.
