Improved Delineation of Arteries in the Posterior Fossa of the Brain by Model-Based Iterative Reconstruction in Volume-Rendered 3D CT Angiography

摘要

Improved CTA delineation of arteries and unruptured aneurysms is clinically desired in the posterior fossa. We present a novel model-based iterative reconstruction that models system statistics and optics to improve CT image quality. We investigated the utility of MBIR for improving delineation of arteries in the posterior fossa on 3D brain CTA.
