Biomedical Ultrasound

Presented by Robin Cleveland, Boston University
Abstract
This tutorial will give a general overview of the use of ultrasound in biomedical applications. It will start with the underlying physics of ultrasound propagation in tissue and review techniques for solving for the acoustic field in the body. This will be followed by a discussion of the processing steps used in current diagnostic ultrasound imaging systems and the challenges that are presented in imaging in the body. We will then proceed to new developments in the field of ultrasound imaging. The tutorial will conclude with a brief synopsis of the therapeutic use of ultrasound.
