SYSTÈME ET PROCÉDÉ POUR ÉLIMINER DU TISSU DUR DANS UNE IMAGE DE TOMODENSITOMÉTRIE

摘要

A system and a method for CT image reconstruction are provided. The method includes: obtaining raw data set related to an object (510); generating a first image set based on the raw data set (710, 520, 530), wherein the first image set includes a first full quality image and a first max field of view image; generating one or more reference images based on the first max field of view image (720); generating a first bone information image based on the one or more reference images (730); generating a second image set based on the raw data set (750), wherein the second image set includes a second full quality image; generating a second bone information image based on the one or more reference images (760); correcting beam hardening artifact of the second full quality image based on the second bone information image to generate a beam hardening artifact corrected image (770).
