Anomalous Relaxation and Diffusion Study Group
Associate Professor Viktor Vegh and a group of international collaborators have set up the Anomalous Relaxation and Diffusion Study Group. The Study Group meets fortnightly via Zoom for a 30-40 minutes live presentation followed by a 20-30 minutes discussion. The first meeting has been scheduled for Friday 1 May, 2020.
If you have an interest in using mathematical models for probing tissue microstructure and constituents, or just in using models for extracting novel information from biologically relevant data, then you may wish to join the Study Group to keep up to date with recent activities within this area.
See the Study Group website for more information and to register for upcoming talks.
We look forward to you joining us.

Fractional Calculus Models of Magnetic Resonance Phenomena: Relaxation and Diffusion
Movement of molecules – their aggregation and dispersal – is the basis of dynamic processes in all physical systems. Tracking molecular trajectories can provide a picture of the structure of materials. Perturbation of water protons by magnetic fields changes the orientation of magnetic moments in ways characterized by relaxation and diffusion. These changes can be measured and visualized using magnetic resonance imaging (MRI). Analysis of the observed signals requires a mathematical model of the process (linear, stochastic, non-linear, multi-scale). Fractional calculus models are one way to capture the complexity of the underlying system. Here, we examine the application of fractional calculus in MRI to T1 and T2 relaxation and to diffusion-weighted signal decay.
