(ADC) A system that receives analog input data and produces digital values at its output. Analog to digital converters are used by the ultrasound scanner to convert the received signal into a format more compatible with the computer systems.
Ultrasound front-end-systems as well as many others sophisticated electronic systems use these analog signal processing components in connection with e.g., low-noise amplifier (LNA), and time gain compensation amplifier (TGC) as key elements in determining the overall system performance.

'China based Shantou Institute of Ultrasonic Instruments (SIUI) has been engaged in the development and manufacture of medical ultrasonic diagnosis scanners, industrial ultrasonic detectors and ultrasonic transducers since the early 1960's. Starting as a small scientific research institute, SIUI has developed into a key high-tech corporation at the national level, and is the leading manufacturer of ultrasonic instruments in China.'
'SIUI is dedicated to providing all customers with the ultrasonic scanners of high quality and reasonable price. The annual production amounts to 5,000 ultrasonic scanners and 10,000 transducers. SIUI takes the lead in attaining ISO9001 certification, FDA clearance and CE marking in China. Due to the high ratio of performance to price as well as the guarantee on quality, the products are exported to over 80 countries and areas around the world. The export volume ranks No. 1 in this field in China. The market share continues to improve.'

'SonoSite, Inc. is the worldwide market and technology leader in high performance, hand-carried ultrasound. Through its expertise in ASIC design, SonoSite is able to offer imaging performance typically found in ultrasound systems weighing more than 300 pounds in a system architecture that is approximately the size and weight of a laptop computer and provides a significant price to performance advantage compared to conventional systems. This breakthrough is transforming and expanding the worldwide diagnostic ultrasound market by serving existing clinical markets more efficiently and creating new point-of-care applications where ultrasound was either too cumbersome or too expensive to be used before. With over 15,000 systems sold since 1999, SonoSite products are known for exceptional performance, ease of use and durability.'

'SonoSite began as a division of ATL Ultrasound in 1997 focused on the development of all-digital, handheld ultrasound devices. In February 1995, the U.S. Defense Advanced Research Project Administration (DARPA) had awarded to ATL a two-year matching grant to develop a highly portable ultrasound device for use on the battlefield or in natural or man-made disasters to diagnose victims of severe trauma. This program culminated with a prototype in October 1998. ATL spun off SonoSite as a public company on April 6, 1998.'

In March 2012 Fujifilm Holdings completes the acquisition of SonoSite.
