Machine settings and technique of image optimization

Abstract

Ultrasound machine settings may be adjusted in order to obtain a good quality image. Knowledge of physical properties of ultrasound and judicious use of basic instrumental controls such as gain, time-gain compensation, frequency, focal zones, depth and field of view will allow the clinician to maximize the diagnostic capability of this modality of imaging in evaluating pelvic floor disorders. This chapter describes the common instrumental controls on ultrasound machines with explanation for how to adjust machine settings to optimize image quality during scanning.
