Ultrasound System Considerations and their impact on Front-End Components Eberhard Brunner analog devices , Inc. 2002 Introduction Medical Ultrasound machines are some of the most sophisticated signal processing machines in use today. As in any machine there are many trade-offs in implementations due to performance requirements, physics, and cost. This paper will try to show the trade-offs for Ultrasound front-end circuits by starting from a high-level System overview followed by a more detailed description of how Ultrasound systems work. Some System level understanding is necessary to fully appreciate the desired front-end integrated circuit (IC) functions and performance, especially for: the Low Noise Amplifier (LNA); Time Gain Control (TGC); and A/D Converters (ADC).
