RAIT 326 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: Admission to the program and permission of the 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
