Holographic microwave imaging for medical applications

Abstract

This paper presents a new 2D holographic microwave imaging array (HMIA) technique for medical imag-ing applications. The HMIA technique has been ap-plied to early stage breast cancer detection and brain stroke detection. Computer models are developed to demonstrate the feasibility of detecting and localizing small brain strokes within a 2D numerical head model and breast tumours within a 3D numerical breast model using the HMIA technique. Experimen-tal validation of the HMIA simulation model using a breast phantom has been undertaken and demon-strated a good agreement between experimental and simulated images. Simulation and experimental re-sults showed that the proposed HMIA technique has the potential to become a powerful medical screening and diagnostic tool.
