The bedside ultrasound is used in the care of sick neonates very often by the treating neonatologist as an extended physical examination. The basic physics involved in the ultrasound technology is very essential to understand the functioning of all the knobs used to derive both the structure and the physiology of the images. This review article covers the essentials of physics including sound, transducers, echogenicity, Doppler, and their interplay to acquire quality images.
