Simulating Ultrasound Reflections Using Rayleigh Integral Method in Complex Biological Media

摘要: This paper exploits the Rayleigh integral method to simulate propagation of transmitted ultrasonic waves and received echoes through various media. Performed simulations study effect apodization using different types windows medium properties on reflections obtained. All estimations are done simplified by Fresnel approximation. Five interfaces considered: tissue-bone-tissue, tissue-fat-bone, fat-muscle-bone, air-fat-bone water-fat-bone. The show that hamming window is more efficient than rectangular triangular for obtaining a consistent beam. In second set simulations, mapped with respect depth from which these generated. It demonstrates solid water media allow attainment deeper regions as compared air medium. Matlab used simulation framework.
