Basic Physics of Diagnostic Ultrasound and Control “Knobology”

This chapter provides an introduction to the basic physics of diagnostic ultrasound. A clear understanding of the principles of ultrasound is vital for appreciating the potential limitations of thoracic ultrasound and interpreting commonly encountered artifacts. The function of the main ultrasound controls will be discussed, and how these can be adjusted to optimize the ultrasound settings to ensure a diagnostic quality image is routinely obtained.
