Abstract

L'objet de cet invention est un nouveau procédé et un dispositif permettant d'améliorer les résolutions énergétiques et spatiales des détecteurs de photons pour application médicale, et plus spécifiquement de caméras basées sur le scintillateur NaI. Pour obtenir la dite amélioration, on utilise un type de filtres construits en éléments très lourds, Z = 74, ou leurs composants. Lesdits filtres sont choisis pour donner de bons résultats avec les émetteurs gamma dont l'énergie est entre 75 keV et 120keV. Un algortihme mathématique approprié permet d'obtenir des images en utilisant seulement des photons qui ne sont pas diffusés à l'intérieur des corps.
