(FDA) An agency of the US federal government established by Congress in 1912 and presently part of the US Department of Health and Human Services. The FDA gives classifications of medical devices according to potential risks and controls the safety of marketed drugs.

(PACS) A system used to communicate and archive medical imaging data, mostly images and associated textural data generated in a radiology department, and disseminated throughout the hospital. A PACS is usually based on the DICOM (Digital Imaging and Communications in Medicine) standard.

The main components in the PACS are: acquisition devices where the images are acquired;
Acquisition devices, which acquire their data in direct digital format, like a MRI system, are most easily integrated into a PACS.
Short term archives need to have rapid access, such as provided by a RAID (redundant array of independent disks), whereas long term archives need not have such rapid access and can be consigned, e.g. to optical disks or a magnetic.
High speed networks are necessary for rapid transmission of imaging data from the short term archive to the diagnostic workstations. Optical fibre, ATM (asynchronous transfer mode), fast or switched Ethernet, are examples of high speed transmission networks, whereas demographic textural data may be transmitted along conventional Ethernet.
Sophisticated software is a major element in any hospital-wide PACS. The software concepts include: preloading or prefetching of historical images pertinent to current examinations, worklists and folders to subdivide the vast mass of data acquired in a PACS in a form, which is easy and practical to access, default display protocols whereby images are automatically displayed on workstation monitors in a prearranged clinically logical order and format, and protocols radiologists can rapidly report worklists of undictated examinations, using a minimum of computer manipulation.

(RIS) Radiology information system means a computer system that stores and processes the information for a radiology department and can be linked to the hospital information system.
The principal purpose of a RIS consists of taking over the general functions of the administration inclusive planning, monitoring and communication of all data regarding patients and its investigations in the radiology. The correct images should reach, at the correct time, the correct users. For this reason the RIS must contain a workflow management in order to simplify and steer the data flow at the individual view stations or devices (laser cameras etc.). The Radiology Information System is optimally complemented with a Picture Archiving and Communication System (PACS).

'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.
