Abstract : This study documents the investigation of ultrasound as a method for diagnosis of atherosclerotic lesions. The study discusses the theoretical background for the use of backscattered radiation on random rough surfaces. The Kirchhoff approximation is used to model the return intensity. Sample surfaces made of sanded Plexiglas, glass beads and aluminum casting are used to compare experimental results with theory prediction. Several arterial tissue samples are used to demonstrate the technique.
