SIMULTANEOUS CT-MRI IMAGE RECONSTRUCTION

摘要

Novel and advantageous systems and method for obtaining and/or reconstructing simultaneous computed tomography (CT) - magnetic resonance imaging (MRI) images are provided. Structural coupling (SC) and compressive sensing (CS) techniques can be combined to unify and improve CT and MRI reconstruction. A bidirectional image estimation method can be used to connect images from different modalities, with CT and MRI data serving as prior knowledge to each other to produce better CT and MRI image quality than would be realized with individual reconstruction.
