This paper describes the design of a microwave stripline applicator for hyperthermic treatment, and the design of an

anatomically based biological model, which is a necessary part of hyperthermia treatment planning for measuring the

distribution of SAR. In this paper we compare the SAR distribution in a cylindrical homogeneous agar phantom (which

lias similar characteristics to biological tissue) and in an anatomically based biological model of the femur (which has been

developed from a computer tomography scan) using a matrix of two applicators of the same type.
