Research Areas
The ultimate goal of our research is to probe cellular structure of living biological tissues using Magnetic Resonance Imaging (MRI). For us, the most promising probes of tissue microstructure are diffusion and transverse relaxation. Our work includes a big portion of theoretical development towards understanding how features of cellular structure and function are reflected in the MRI signal. This research spans the range between physics-type experiments with artificial samples to real clinical measurements.
We also respond to the challenge of the ill-posed inverse problem of finding relevant microstructural features if living tissues given measured data. Our group possesses the necessary expertise in advanced data processing.
We also focus on MR methods that could elucidate microstructural specifics. Measurement techniques developed in our group are tailored in agreement with theory to provide tractable experimental data.
In practical implementation, we develop global fiber tracking that exploits diffusion MRI for reconstructing macroscopic tracts with microscopic properties of the tissue compartments, dynamic measurements of cerebral perfusion and vessel size imaging. All clinically relevant methods are verified in collaboration with our clinical partners.
