Abstract
Système d'imagerie spectroscopique des tissus organiques dans lequel un élément de stockage optique (1500) et un dispositif à couplage de charge sont utilisés pour obtenir une image précise des tissus choisis. Une source de rayons X produit des rayons X qui traversent une région du corps du sujet, formant une image radiographique qui atteint l'élément de stockage optique (1500). Celui-ci (1500) émet par rayonnement un motif d'intensité spatial correspondant à l'image, ce motif étant détecté par un capteur à dispositif à couplage de charge. L'image est numérisée par le capteur et traitée par un régisseur avant d'être stockée sous forme d'image électronique. Chaque image est envoyée à un dispositif à couplage de charge associé correspondant, ou à un détecteur au silicium amorphe, ce qui donne des représentations électroniques individuelles des images séparées. L'élément de stockage optique (1500) est placé dans un manchon (1500) inséré dans la bouche du patient, à proximité des dents à radiographer. Un élément (1502) absorbant les rayons X émis est également inséré par glissement dans le manchon (1504).
