Contrast-medium anisotropy-aware tensor total variation model for robust cerebral perfusion CT reconstruction with weak radiation: a preliminary study

In this study we present a novel contrast-medium anisotropy-aware TTV (Cute-TTV) model to reflect intrinsic sparsity configurations of a cerebral perfusion Computed Tomography (PCT) object. We also propose a PCT reconstruction scheme via the Cute-TTV model to improve the performance of PCT reconstructions in the weak radiation tasks (referred as CuteTTV-RECON). An efficient optimization algorithm is developed for the CuteTTV-RECON. Preliminary...
