DMSU 211 Ultrasound Physics and Instrumentation I

This course explains how the pulse-echo principle is used in sonography. Basic sound and ultrasound physics are covered, including frequency, wavelength, propagation speed, reflection, and resolution. The components and function of the ultrasound transducer and equipment are explored.
