Title
(EN) DIGITAL DETECTOR
(FR) DÉTECTEUR NUMÉRIQUE
Abstract
(EN) An extra-oral dental imaging apparatus for obtaining an image from a patient has a radiation source and a digital imaging sensor that provides, for each of a number of image pixels, at least a first digital value according to a count of received photons that exceed at least a first energy threshold. A mount supports the radiation source and the digital imaging sensor on opposite sides of the patient's head. There can be a computer in signal communication with the digital imaging sensor for acquiring one or more two-dimensional images.
(FR) Cette invention se rapporte à un appareil d'imagerie dentaire extra-orale destiné à obtenir une image à partir d'un patient qui présente une source de rayonnement et un capteur d'imagerie numérique qui fournit, pour chacun d'un certain nombre de pixels d'image, une première valeur numérique au moins selon un compte de photons reçus qui dépasse au moins un premier seuil d'énergie. Un support supporte la source de rayonnement et le capteur d'imagerie numérique sur des bords opposés de la tête du patient. Il peut y avoir un ordinateur en communication de signal avec le capteur d'imagerie numérique de façon à acquérir une ou plusieurs images bidimensionnelles.
