Radiation image acquisition device in real time

Creators

Description

The device is made of a radioluminescent screen receiving a radiation image, a photodetector-memorizer receiving the luminous radiation from the screen, optical means focusing the radiation on the photodetector-memorizer, and process means. The photodetector-memorizer is made of a charge integration photodetector matrix to which one or several shift registers are associated. The luminescent screen material is doped suitably to have an optimized emission with regard to the photodetector matrix sensitivity

Abstract (French)

Ce dispositif comprend un ecran radioluminescent recevant une image de rayonnement d'un objet a irradier expose au rayonnement d'une source d'irradiation S, un photodetecteur memorisateur recevant les signaux lumineux issus de l'ecran radioluminescent, des moyens optiques focalisant le rayonnement lumineux issu de l'ecran radioluminescent sur le photodetecteur-memorisateur et des moyens de traitement. Il se caracterise en ce que le photodetecteur-memorisateur est constitue d'une matrice de photodetecteurs a integration de charges de types DTC a laquelle sont associes un ou plusieurs registres a decalage. Le materiau constituant l'ecran radioluminescent est dope convenablement pour obtenir une emission optimisee au regard de la sensibilite des matrices de photodetecteurs. Cette invention trouve notamment son application en imagerie medicale
