Physics of ultrasound

Abstract

Medical practice of ultrasound is constantly expanding. It is now used for not only screening and diagnosis of various diseases, but also to enhance care in the field of anaesthesia and intensive care. Ultimately, the quality of care depends on imaging quality. Practitioners of ultrasound therefore need to understand the physics and principles behind the technology in order to create optimal images. In this article, we will remain focused on the basic principles of physics and their applications in the relevant clinical practice.
