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)
- Whole-brain B1 mapping for correction of quantitative MRI data
- Quantitative MRI and voxel-based quantification (VBQ)
- Reduction of susceptibility artifacts in functional MRI (fMRI)
- Improvements in data acquisition & artefact correction for diffusion MRI
- Physiological noise correction in fMRI
- Real-time fMRI (rtfMRI) and neurofeedback of the BOLD response
- Voxel-based cortical thickness (VBCT) measurements
- Development of raw data post-processing techniques for image artefact suppression
- Concurrent TMS and fMRI
- Parallel imaging and generalized image reconstruction
- Artefact correction in diffusion MRI (ACID) - SPM Toolbox
