RAIT 326 Sonographic Physics for non-Sonographers • 5 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. This course is intended to meet the degree requirements of the Technology concentration as well as the requirements of the Breast Ultrasound certificate of the Radiation & Imaging Sciences program and requires ARRT(R) or ARDMS credential. Prerequisites: Admission to the Radiation & Imaging Sciences program or 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
- Anticipate and evaluate reflection characteristics based on acoustic impedance calculations
- Calculate levels of attenuation in tissue
- Describe and discuss the operational characteristics of an ultrasound transducer
- Apply the concepts of resolution and focusing to obtain the optimum image; evaluate the image for quality
- Describe how the ultrasound instrument processes electrical and sonographic information into multidimensional images
- Describe, discuss, contrast, compare, and identify the Doppler effect in a spectral display
- Evaluate image artifacts and explain them using reasonable physical principles
- Discuss the ALARA philosophy, bioeffects of insonation concerning the mechanical index and thermal index
