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.
Hours Weekly
2.5 hours theory, 2 hours on-campus lab weekly
Course Objectives
- Explain how the pulse-echo principle is used in sonography.
- Demonstrate weakening of ultrasound as it travels through tissue.
- Explain the generation of echoes in tissue.
- Demonstrate how sonographic instruments work.
- Discuss frequency and its importance to diagnostic ultrasound.
- Explain the process by which ultrasound pulses are generated, and the path they travel.
- Categorize a sound beam and list the factors that affect it.
- Illustrate how sound beams are automatically focused and scanned through tissue cross sections.
- Compare signal processing with image processing.
- Discuss temporal resolution and the factors that influence it.
- Explain how images are stored electronically.
- Compare linear, convex, phased, and vector arrays.
- Categorize the common display modes.
