Broadband dielectric properties of adrenal gland for accurate anatomical modelling in medical applications

Dielectric properties of biological tissue are important in safety assessment and evaluation of novel medical imaging and therapeutic devices. This paper reports frequency dependent dielectric properties of adrenal tissue, which is a potential target for microwave ablative therapy to treat benign and malignant adrenal tumors. Dielectric properties of bovine adrenal glands were measured using open-ended coaxial probe over 0.5 to 20 GHz, and a two pole Cole-Cole model was fitted to the measured data. The parameters of Cole-Cole model are presented in this paper.
