DMS 101 - Sonography Principles and Instrumentation I
Description: Foundational concepts of diagnostic ultrasound through the study of wave mechanics, acoustic propagation, and sound-tissue interactions. Explore the physical characteristics of sound, the formation of pulses, and the behavior of acoustic energy in the human body. Emphasis is placed on understanding how physical principles directly influence image formation and diagnostic quality.
