Abstract

On emploie un nombre considérablement réduit de détecteurs (200/202) de cristaux de scintillation/rayons gamma de tubes photomultiplicateurs (TPM), dans un réseau annulaire se trouvant autour d'un volume d'images (212) de tomographie par émission de positrons (TEP). Du fait du nombre relativement faible desdits détecteurs, la complexité et le coût de canaux de traitement de signaux électroniques associés est considérablement réduit (même si chacun desdits canaux est doté de capacités de temps de vol sophistiquées). De plus, comme l'on utilise un nombre de cristaux relativement plus faible, il devient possible d'utiliser des cristaux de scintillation (200) beaucoup plus grands et un temps de réponse plus rapide, de manière à augmenter puissamment l'efficacité de détection des rayons gamma ainsi que le rejet des diffusions, tout en permettant également aux circuits électroniques (204) de mieux rejeter les événements aléatoires et de produire un temps effectif de filtrage de données d'images de vol. Le fait de prévoir une ouverture de collimation (206) décalée successivement pour chaque détecteur successif (200) du réseau annulaire, et le fait de mettre en rotation (300) le réseau dans un grand nombre de positions d'angles de vue successifs, permet d'acquérir des données d'images de résolution extrêmement élevée à un prix de revient du système considérablement réduit.
