Microwave Differential Imaging of Myocardium for Assessment and Therapeutic Monitoring of Transcatheter Cardiac Ablation

Start year: 2003

Summary: We propose to develop Microwave Imaging techniques for cardiovascular disease diagnosis at 2.45 GHz. Firstly, we aim to image the contrast in the complex dielectric constants of healthy and ischaemic heart tissue. The second aim is to image the extent and efficacy of therapeutic lesion formation due to cardiac ablation modalities. We propose to develop a cylindrical antenna array for near field microwave imaging using novel wire antenna elements. Fast and iterative reconstruction algorithms based on electromagnetic scattering and computational techniques will also be developed.''
