The image reconstruction is performed using an iterative reconstruction method to minimize a cost function including a data-fidelity term (e.g., a system-matrix term) and a regularization term. The system-matrix term includes a weighted inner-product of the system-matrix equation, wherein the weighting matrix includes weighting values to correct the unequal data redundancy of the gated projection data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for iteratively reconstructing tomographic images from electrocardiographic-gated projection data","description":"An apparatus and method for computed tomography (CT) imaging to obtain an image from gated projection data, such as electrocardiographic gated projection data used in cardiac CT.
