Introduction to Ultrasound Physics and POCUS
Overview
In this chapter, we introduce the students to the basic principles of ultrasound, including the physics involved in generating an ultrasound image as well as other technical jargons. We begin by discussing the physics involved in ultrasound. Then we proceed to describe on how it is generated and how it behaves when travelling in between different types of tissues.
