More Information
Summary:Embodiments include a method, comprising: receiving measured radiation obtained from a radiation detector that received radiation through an object; simulating the measured radiation obtained from the radiation detector that received radiation through the object; generating an offset based on the measured radiation and the simulated measured radiation; estimating scatter radiation based on the offset; and estimating primary radiation based on the estimated scatter radiation Des modes de réalisation comprennent un procédé consistant : à recevoir un rayonnement mesuré obtenu en provenance d'un détecteur de rayonnement ayant reçu un rayonnement à travers un objet ; à simuler le rayonnement mesuré obtenu en provenance du détecteur de rayonnement ayant reçu un rayonnement à travers l'objet ; à générer un décalage en fonction du rayonnement mesuré et du rayonnement mesuré simulé ; à estimer un rayonnement de diffusion en fonction du décalage ; et à estimer un rayonnement principal en fonction du rayonnement de diffusion estimé.
