Introduction to Ultrasound // Physics + Knobology

Hello learners! If you’ve reached this page you are likely curious about learning how to use ultrasound, know a little bit about ultrasound and want to learn more, or are an experienced bedside sonographer looking to review the fundamentals.  Regardless of which category you fall into, I have compiled below a handful of the videos/resources that first helped me to learn ultrasound.  Understanding these basics and fundamentals is KEY to your future success of mastering the art of POCUS (point-of-care ultrasound).  I recommend watching all of the videos below in their entirety until you feel comfortable with the underlying physics, basic knobology, and foundational terminology that you will need moving forward.  That being said, you may want to watch these videos several times.
