Measuring the Reliability of Geometries in Magnet Resonance Angiography A Reference for Multimodal Image Registration? (2009)

M. André Gaudnek, Andreas Hess, Klaus Obermayer, Michael Sibila

Abstract. Magnet Resonance Angiography (MRA) can be used to register MR images of other types (e.g. functional MRI) acquired in the same imaging session as the angiogram since blood vessels are...

Adaptive Threshold Masking An Extended Bias Correction Algorithm for Heavily Biased MR Images (2009)

M. André Gaudnek, Andreas Hess, Klaus Obermayer, Michael Sibila

Abstract. Image bias is a usual phenomenon in MR imaging when using surface coils. It complicates the interpretation as well as the algorithmic postprocessing of such data. We introduce a bias...
