DUTEC 250 Ultrasound Physics for Mammographers • 3 Cr.
Covers acoustical physics, including the concepts and principles of sound transmission, and the utilization of high frequency sound to produce images for diagnostic purposes. Prerequisite: Acceptance into program; or permission of program chair.
After completing this class, students should be able to:
- Identify, contrast, and compare the various types of mechanical waves and the sound spectrum
- Calculate frequency, wavelength, intensity, and identify relative sizes of objects
- Anticipate and evaluate reflection characteristics based on acoustic impedance calculations
- Discuss and note the differences between specular, diffuse, and Rayleigh scatterers
- Calculate levels of attenuation in tissue
- Describe and discuss the operational characteristics of an ultrasound transducer
- Describe, discuss, contrast, and compare the concepts of an array of elements and beam formation
- Apply the concepts of resolution and focusing to obtain the optimum image; evaluate the image for quality
- Calculate the range in a pulse-echo event
- Describe, discuss, contrast, compare, and identify the Doppler effect in a spectral display
- Identify and evaluate image artifacts and explain them using reasonable physical principles
- Develop an appreciation for the importance of physics in understanding and using ultrasound techniques
