Feasibility for Ultrasonic Characterization of the Surface Roughness ofAtherosclerotic Plaque

摘要

This study documents the investigation of ultrasound as a method for diagnosis ofatherosclerotic 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. Ultrasound, Diagnosis, Atherosclerotic lesions, Backscattered radiation, Surface roughness.
