Title (EN) METHOD AND DEVICE FOR PROCESSING COMPUTERIZED TOMOGRAPHY IMAGES
(FR) PROCÉDÉ ET DISPOSITIF POUR TRAITER DES IMAGES DE TOMODENSITOMÉTRIE
Abstract: front page image
(EN)A method of processing a computerized tomography image is disclosed. The method comprises preprocessing the image using contrast enhancement weight function, thereby providing a preprocessed image having a first dynamic range; and applying a companding procedure to the preprocessed image, so as to reduce the first dynamic range.
(FR)L'invention porte sur un procédé consistant à traiter une image de tomodensitométrie. Le procédé comprend le prétraitement de l'image à l'aide d'une fonction de pondération d'amélioration de contraste, fournissant ainsi une image prétraitée présentant une première plage dynamique; et l'application d'une procédure de compression-extension à l'image prétraitée, de façon à réduire la première plage dynamique.
