ADI 211 - Sonography Prin & Instrumentation II

Credit(s) 2.00
Lecture Hours: 2.00
This course examines the instrumentation used to generate and receive sound waves for medical imaging purposes with respect to their design and operating characteristics. The hemodynamics of blood flow in the human body and the physical principles of Doppler ultrasound techniques are studied. Continuous wave, pulsed wave, color flow, power Doppler, as well as emerging technologies will be explored. Students will evaluate both gray scale and color images as well as spectral tracings as they study data acquisition methods and learn to identify normal versus abnormal display patterns associated with the vascular system. Quality assurance standards and methods of equipment testing are emphasized as image and display characteristics are evaluated. The relationship between intensity levels and exposure time are also addressed as they relate to the potential for bioeffects in human tissue.

Prerequisite(s): A minimum grade of C in ADI 111, ADI 321, and ADI 840.
SLOs:
Upon successful completion of this course, students will be able to:

Compare various types of pulse-echo instruments, their components and the principle of operation of each.
Select appropriate equipment and/or adjust operating factors to optimize the display and recording of images.
Explain the physiologic and anatomic factors that influence blood flow.
Summarize the Doppler effect.
Explain how Doppler frequency shifts are used to detect and evaluate blood flow.
Describe the basic principle and operation of Doppler instruments.
Summarize common imaging artifacts and methods used to utilize or eliminate them.
Identify the potential risk for bioeffects as sound propagates in media.
Rephrase concept of As Low As Reasonably Achievable (ALARA).
