We have developed a microwave imaging device for breast cancer imaging that can be used concurrently inside an MR imaging system. The microwave measurement system is comprised of a horizontal array of 16 monopole antennas that can be moved vertically for full 3D coverage of the breast. All compatibility issues have been addressed. The motion is achieved using a novel 3D printed gearing device. Initial results demonstrate that the system is capable of accurately recovering the size, shape, location and properties of a 3D shape varying object. This is a critical step towards clinical microwave breast imaging in the MR.

This paper aims to explore the potential of a novel radiometry technique that leverages bio-matched antennas (BMAs), broadband measurements, and forward modeling of layered tissues for non-invasive and accurate core temperature monitoring. Our approach relies on the observation that electromagnetic waves penetrate to different depths depending on their frequency and dielectric properties of the medium and adapts radiative transfer models that have been successfully implemented in the past for layered geophysical media. Preliminary modeling and experimental results confirm feasibility.
