Title (EN) COMPUTERIZED TOMOGRAPHY UNIT
(FR) UNITE DE TOMOGRAPHIE INFORMATISEE
Abstract:
(EN) A computerized tomography unit employing means that is simply constructed without requiring any particular control mechanism to process the data within short periods of time and to measure view data produced by radiated rays of a plurality of photon energy levels through a single scan by a radiated beam. In the computerized tomography unit of the invention, different photon energy characteristics are established between one side and the other side with the center of a multi-channel radiated ray detector as a boundary, the periphery of a sample is scanned in a rotating manner with a fan beam radiated ray, so as to utilize a pair of measured values by radiated rays that pass in the opposite directions through the same portion of the sample.
(FR) Unité de tomographie informatisée utilisant un mécanisme construit simplement sans nécessiter de mécanisme de commande particulier pour traiter les données pendant de courts laps de temps et pour mesurer les données de vues produites par les rayons d'une pluralité de niveaux d'énergie photonique grâce à un simple balayage au moyen d'un faisceau de rayonnement. Dans l'unité de tomographie informatisée de la présente invention, différentes caractéristiques d'énergie photonique sont établies entre un côté et l'autre, le centre d'un détecteur de rayons multicanaux servant de frontière, la périphérie d'un échantillon est balayée d'une manière rotative au moyen d'un rayon de faisceau en éventail, de manière à utiliser une paire de valeurs mesurées par des rayons passant dans des directions opposées à travers la même partie de l'échantillon.
