Abstract

L'invention concerne un système d'imagerie pour l'imagerie par balayage à conversion directe et à rayonnement de haute énergie, comportant une source de rayonnement de haute énergie et un dispositif d'imagerie à conversion directe et à rayonnement de haute énergie semiconducteur, arrangé autour d'une position de l'objet. Ce dispositif d'imagerie comporte une pluralité de cellules d'imagerie, comportant chacune une cellule détecteur et une cellule d'affichage destinée à produire des valeurs de sortie de cellule d'imagerie, représentatives de l'incidence d'un rayonnement de haute énergie sur la cellule détecteur. L'élément de source et/ou le dispositif d'imagerie sont arrangés pour se déplacer de manière sensiblement continue l'un par rapport à l'autre, pour balayer un objet au niveau de la position de l'objet. Les cellules d'affichage fonctionnent pour lire les valeurs de sortie des cellules d'imagerie, à des intervalles de temps qui correspondent sensiblement à un point d'image de l'objet traversant la moitié de la distance d'une zone ou d'une cellule détecteur dans la direction du balayage. Une telle configuration permet une résolution au niveau pixel au cours de l'opération de balayage.
