Catalog Description:
This course will provide knowledge of Ultrasound Physics and Instrumentation;
Including: Sonographic principles, Doppler principles, Artifacts, Performance and Safety.
Prerequisites: Admission to the Diagnostic Medical Sonography Program.
Course Learning Outcomes:
Upon completion of this course the student will be able to:
1. Explain how the pulse-echo principle is used in sonography.
2. Describe the image formats used in sonography.
3. Explain how the Doppler effect is applied in Doppler ultrasound.
4. Explain what frequency is and why it is important in diagnostic ultrasound.
5. Define ultrasound and describe how it behaves.
6. Discuss how harmonics are generated.
7. Describe the weakening of ultrasound as it travels through tissue.
8. Describe the construction of a transducer and the function of each part.
9. Explain how a transducer generates ultrasound pulses and receives echoes.
10. Describe a sound beam and list the factors that affect it.
11. List the factors that determine detail resolution.
12. List the primary components of sonographic instruments.
13. List and compare the various kinds of flow encountered in blood circulation.
14. Define and discuss the Doppler effect, shift and angle.
15. Explain how two-dimensional flow information is color-encoded on a
sonographic display.
16. List various reasons why sonographic gray-scale images can present anatomic
structures incorrectly (artifacts).
17. Explain how an operator of an ultrasound instrument can implement the ALARA
principle by minimizing exposure of the patient to ultrasound during diagnostic
scanning.

available to discuss appropriate accommodations with students. Please contact the ADA
Officer (Julie Byrnes) at 775-753-2271 at your earliest convenience to request timely and
appropriate accommodations.
Instructional Methods:
Teaching methods will include lecture, group discussions, learning exercises, class
participation exercises, demonstrations and examinations. A variety of other techniques
may be used to develop knowledge, skills and attitudes.
Grading Criteria:
All students must maintain a GPA of 2.5 or above to continue in the Diagnostic Medical
Sonography program. A minimum grade of a “C” (75%) is required in the Diagnostic
Medical Sonography program.

Late Policy: For each day an assignment is late, 5% will be deducted from the total
grade for that assignment.
Assignments: For each chapter there is a series of review questions that need to be
completed by the next week’s class. These review assignments will be worth 40% of the
overall grade. Quizzes will be worth 30% of grade. The Final Exam is worth 30% of
grade. May do test corrections for one half credit.
The test corrections must be turned in by email or at my office by the end of finals
week or no extra credit will be given. The test corrections must be typed. There
needs to be one space between each answer. The page number from the book
must be included with the corrections.
