DIVISION OF HEALTH PROFESSIONS
DIAGNOSTIC MEDICAL SONOGRAPHY PROGRAM
DMS 101
1 lec., 3 lab., 2 credits
Co-requisites: DMS-102, DMS-113, DMS-115
COURSE DESCRIPTION: Ultrasound Physics and Instrumentation I will provide the student with the relevant
fundamental physical properties as the basic instrumentation used in diagnostic ultrasound. Modes of operation, imaging
and display techniques that relate to high frequency sound production will be stressed.
GENERAL COURSE OBJECTIVES: At the conclusion of this course, the student will be able to:
Discuss how ultrasound can produce images of the human body.
Define the parameters of a sound wave as well as the parameters of pulsed ultrasound.
Define all terms related to ultrasound physics.
Demonstrate how to use equipment related to ultrasound.
Select the proper transducer for any ultrasound procedure.
Explain the role of each component of an ultrasound instrument.
Adjust ultrasound machine controls to obtain a diagnostic image.
REQUIRED TEXTBOOK: Kremkau, Frederick W. DIAGNOSTIC ULTRASOUND: PRINCIPLES AND
INSTRUMENTS. Eighth edition. W.B.Saunders Company. Philadelphia. 2011.
COURSE POLICIES:
1. In addition to scheduled tests, a quiz on the previous week’s material will be administered prior to each lecture.
2. Missed quizzes (due to absenteeism or tardiness) cannot be made up. The lowest quiz grade will be dropped.
3. A physicians note must be submitted for any absence on a scheduled test day. The missed test must be made up in the
Testing Center before the next class meeting.
4. If recording devises are encouraged and must be used in a manner that is not disruptive to the class. A voice activated
unit is recommended.
5. Cell phone use in the classroom is prohibited.
ASSESSMENT: Knowledge of course objectives will be assessed by verbal questions prior to, and at the end
of each class, quizzes, tests, and lab worksheets.
