Ultrasound imaging has been established as a valuable, safe, generally non-invasive technique that enables physicians to visualize internal structures in many clinical settings. As the technology has advanced, two dimensional (2D) imaging has evolved to real-time three dimensional (sometimes called 4D) views to analyze motion. Initially, cardiology and obstetrics served as primary clinical applications for both diagnostic and interventional ultrasound studies. Currently, clinicians across the health spectrum have recognized the power of this imaging modality for initial diagnostic procedures, for interventional procedures, and for long-term evaluation and follow-up.

Leading-edge vendors have developed new capabilities through improvements in transducers, and by leveraging the computing power of high-speed processors. Besides technical advances, manufacturers have recognized a growing problem for sonographers: repetitive motion injuries such as carpal tunnel syndrome. New, more ergonomic models of ultrasound equipment are designed to reduce stress on the joints of personnel who perform examinations.

GE Medical Systems (GEMS of Waukesha, Wis.), added ComfortScan features to its LOGIQ9, and Vivid 7 ultrasound equipment with a floating user interface that moves in all directions to enable the user to adjust the operator’s console to an ergonomically correct height and position. Siemens Medical Solutions Ultrasound Division’s (Mountain View, Calif.) new release, the Sonoline G60S system, is compact for portability and features lightweight cables and transducers designed to reduce stress on the operator’s arms, hands and wrists.

“The U.S. Market for ultrasound grew 10 percent from 2000 to 2001,” says Ken Olsen, medical imaging industry analyst for Frost & Sullivan (San Jose, Calif.). While doubting that this trend is sustainable, he suggests that the growth rate should remain in the high single digits. “Procedures have increased from 79 million in 2000 to 83 million, which represents a 5 percent increase growth rate in 2002, and should at the very least remain at this level if not grow.”
