Abstract :
A novel method for location and characterization of discontinuities in biological systems is presented. The method uses electromagnetic waves in the microwave and RF region and a modified algorithm previously used for the estimation of the angle of arrival of radar signals. Results are presented for the case of a skull section backed by porcine brain and the same section backed by a layer of blood backed by porcine brain
