• BIOEN 449/549 Ultrasound Imaging

    This is a comprehensive course on ultrasound imaging for engineering and science students. 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 beamforming and image formation are covered next 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 also include nonlinear tissue imaging and contrast agents with special emphasis on nonlinear pulsing schemes as well as 3D imaging and elastography.

  • BIOE 448/548 Bioacoustics and Therapeutic Ultrasound

    This course provides junior/senior undergraduate and graduate level engineering and science students with fundamentals of acoustics and ultrasound relevant for bioengineering-type applications. The course spends the first half covering the physical principles of sound waves/ultrasound propagating in tissue. Topics include the wave equation, acoustic impedance, reflection and transmission of sound, refraction, basic signal processing, sound beams, transducers, ultrasound attenuation, and scattering. The second half of the course covers therapeutic ultrasound with emphasis on bubble dynamics and drug delivery, lithotripsy, high intensity focused ultrasound for thermal ablation.
