A Unified Variational Approach to Denoising and Bias Correction in MR
Abstract. We propose a novel bias correction method for magnetic resonance (MR) imaging that uses complementary body coil and surface coil images. The former are spatially homogene...

Statistical Study on Cortical Sulci of Human Brains
A method for building a statistical shape model of sulci of the human brain cortex is described. The model includes sulcal fundi that are defined on a spherical map of the cortex. ...

Estimation of Baseline Drifts in fMRI
This work provides a new method to estimate and remove baseline drifts in the fMRI signal. The baseline drift in each time series is described as a superposition of physical and ph...

Tracking Brain Deformations in Time-Sequences of 3D US Images
During a neurosurgical intervention, the brain tissues shift and warp. In order to keep an accurate positioning of the surgical instruments, one has to estimate this deformation f...
