Title (EN) SYSTEM AND METHOD FOR GENERATING A TOMOGRAPHIC RECONSTRUCTION FILTER
(FR) SYSTÈME ET PROCÉDÉ DE GÉNÉRATION D'UN FILTRE DE RECONSTRUCTION TOMOGRAPHIQUE
Abstract:
(EN) A system for generating a reconstruction filter for an imaging scanner comprises a model bank (124) that includes a model for generating the reconstruction filter, a filter criteria bank (122) that includes filter criteria for generating the reconstruction filter, and a filter generator (120) that generates the reconstruction filter based on the filter model and the filter criteria. In one non-limiting instance, the model is based on minimizing a cost function that includes predetermined filter criteria such as image contrast. In another non- limiting instance, the cost function includes terms relating to spatial resolution, noise and a signal visual perception in the presence of noise.
(FR) Un système de génération d'un filtre de reconstruction destiné à un scanneur d'imagerie comprend une banque de modèles (124) qui contient un modèle permettant de générer le filtre de reconstruction, une banque de critères de filtre (122) qui contient les critères de filtre permettant de générer le filtre de reconstruction, ainsi qu'un générateur de filtre (120) qui génère le filtre de reconstruction sur la base du modèle de filtre et des critères de filtre. Dans un exemple non limitatif, le modèle est basé sur la réduction au minimum d'une fonction de coût qui contient les critères de filtre prédéfinis, tel le contraste d'image. Dans un autre exemple non limitatif, la fonction de coût contient des termes relatifs à la résolution spatiale, au bruit et à la perception visuelle d'un signal en présence de bruit.
