Abstract
In developing a microwave tomography system, we started by examining the fundamental signal measurement challenges-i.e.,
how to interrogate the target while suppressing unwanted multi-path signals. Beginning with a lossy coupling bath to suppress
unwanted surface waves, we have developed a robust and reliable system that is both simple and low profile. However, beyond the
basic measurement configuration, the lossy coupling medium concept has also informed our choice of array antenna and imaging
algorithms. The synergism of these concepts has produced a novel concept which is embodied in a system that has been successfully
translated to the clinic.
