The physics and technique of ultrasound

Abstract

Ultrasound performed and interpreted by the clinician combines knowledge of the anatomy and disease processes with technical expertise to produce images of superior quality which answer a specific clinical question. An understanding of the physical principles of ultrasound, proper probe selection and machine settings is critical to obtaining high quality diagnostic images. This chapter will describe the physical principles of ultrasound along with an explanation for how to adjust machine settings to correct for common ultrasound artifacts.
