Abstract

An approach for obtaining both a high-resolution and high-contrast 3D MRI image volume, desirable for image-guided minimally invasive brain surgery, is proposed. Current MRI imaging techniques, especially in situations where contrast requirements dictate use of T2- weighed sequences with long repetition times, do not deliver sufficient resolution in the cross-slice direction. As SRR techniques can be very attractive for obtaining isotropic 3D MRI images from the anisotropic 2D multi-slice volumes, we adopt in this work a MAP super-resolution method with modified regularization parameters. Experiment results demonstrate that resolution enhancement and better edge definition are obtained. © 2013 Production and hosting by Elsevier B.V.
