Novel techniques for UWB microwave imaging of objects with canonical shape

This paper describes the development of a new algorithm for use in a recently established technique for medical imaging based on ultrawideband (UWB) microwave signals rather than ionizing radiations such as x-rays. The method is based on Huygens principle (HP), which removes the need to solve inverse problems and, consequently, the need for matrix generation/inversion. In addition to its simplicity, it is shown that HP enables the detection of the extent to which different tissues, or differing conditions of tissues, can be discriminated and render contrast in the final image. Validation of the technique through measurement on cylinder with inclusions is presented.
