BIOEN 449/549 Therapeutic and Diagnostic Ultrasound
This is a comprehensive course on ultrasound as used in biomedical applications for engineering and science students. The course covers both diagnostic and therapeutic applications of ultrasound. An introductory level knowledge on ultrasound imaging is preferred but not necessary. The physical principles of ultrasound necessary for explaining diagnostic ultrasound are covered first. These include wave propagation, reflection and transmission of sound at interfaces, scattering, attenuation, acoustic impedance, signals, and Fourier analysis. Array beam forming and image formation are covered in detail. The main imaging modes of clinical diagnostic ultrasound systems are presented and explained in lectures, homework problems and hands on laboratory exercises. Topics include nonlinear tissue imaging and contrast agents with special emphasis on nonlinear pulsing schemes as well as 3D imaging and elastography. Therapeutic applications of ultrasound are covered such as tissue ablation with High Intensity Focused Ultrasound (HIFU). The heat transfer process is explained with theoretical models like the Bioheat equation. Mechanical effects of ultrasound such as cavitation in lithotripsy and histotripsy are covered. Ultrasound-mediated drug delivery approaches which rely on both thermal and mechanical effects of ultrasound are covered.
