Title (EN) METHOD FOR IMPROVING THE SPATIAL RESOLUTION OF A COMPTON CAMERA
(FR) PROCEDE D'AMELIORATION DE LA RESOLUTION SPATIALE D'UNE CAMERA COMPTON
Abstract:
(EN) A Compton camera has two detectors which each sense the location, energy and time of photon collisions. Compton events are detected in which a photon emanating from the subject collides with one detector at energy (E1) and then the second detector at (E2), both energies E1 and E2 are measured and used in conjunction with an initial photon energy E0 to increase the resolution of the camera.
(FR) Cette invention se rapporte à une caméra Compton comportant deux capteurs conçus chacun pour détecter l'emplacement, l'énergie et l'instant de collisions des photons. On décèle les événements à effet Compton au cours desquels un photon émanant du sujet entre en collision avec un des capteurs à une énergie (E1) puis avec l'autre capteur à une énergie (E2), on mesure à la fois l'énergie E1 et l'énergie E2 et on utilise ces mesures d'énergie ainsi que l'énergie initiale E0 des photons pour accroître la résolution de la caméra.
