MRI Physics

Dr Nikolaus Weiskopf

The laboratory pursues brain research by means of functional and structural imaging.

The laboratory is equipped with a 3 T head scanner (Siemens Allegra), two 3 T whole body scanner (Siemens Tim Trio inc. 32-ch head coil), an MEG system (CTF/VSM), two EEG systems (one being MR compatible) and an MR compatible TMS system.

The physics group supports ongoing research projects by developing innovative MR imaging techniques, pulse sequences, novel data processing methods, software for the presentation of stimuli, and MR compatible hardware components.

Our main research interests comprise (see also Physics publications):

• High-resolution functional MR Imaging (fMRI) and anatomical MRI
• Quantitative MRI and voxel-based quantification (VBQ)
• Reduction of susceptibility artifacts in functional MRI (fMRI)
• Physiological noise correction in fMRI
• Real-time fMRI (rtfMRI) and neurofeedback of the BOLD response
• Voxel-based cortical thickness (VBCT) measurements
• Optimisation of Diffusion Tensor Imaging (DTI) sequences for fibre tracking
• Development of raw data post-processing techniques for image artefact suppression
• Concurrent TMS and fMRI
• Parallel imaging and generalized image reconstruction
• SPM Toolboxes for DTI
