Biomechanics for Breast Cancer Imaging

Modelling breast deformation during various imaging modalities (Xray, MRI, CT) with applications to cancer detection. A collaborative study with Dr Ralph Highnam (Matakina Technology Ltd).

Electrocardiographic imaging

Heart and body ECG mapping during normal sinus rhythm, ventricular pacing, localised ischaemia, abnormal ventricular automaticity, hyperkalaemia. Development and validation of inverse ECG modelling methods to electrically image the heart non-invasively.

Cardiac Mechanics

Mathematical modelling and mechanics of the beating heart using the finite element method (FEM). Implementation of efficient optimisation algorithms and parallel processing techniques (based on the FEM) to estimate material properties and to predict accurate distributions of mechanical stress throughout the ventricular walls during the heart cycle.
