The evaluation of non-invasive microwave thermometry using a differential microwave imaging approach is investigated in an experimental setup. The setup consists of a monopole microwave tomographic system, a muscle phantom, and a circulation/heating system. The saline solution is used as the heated medium inside the muscle phantom. Based on Born Approximation and regularization by TSVD we reconstructed the distribution of both dielectric parameters, relative permittivity and electrical conductivity inside the investigation area. A promising agreement between measured and reconstructed electrical conductivity was achieved and some specifics for future improvement of microwave thermometry were identified.
