Ardent Sound, Inc. Announces FDA Clearance for Voyager(TM) Compact Ultrasound Imaging System

The Company announces they have received a 510(k) approval for the Voyager(TM)
Compact Ultrasound Imaging System and will begin shipping devices in April. 

Voyager(TM) is first in the Ardent Sound family of products designed to function
as a peripheral with a standard laptop or desktop personal computer. "It is an ultra portable system that rivals the resolution and diagnostic quality of mid and high-end systems from the recent past, while costing a fraction of the price of mid and high-end units available today", states Michael Slayton, CEO.  "Our intent was to develop lightweight, portable ultrasound imaging devices with image quality good enough to improve clinical care in the radiology suite and in the many diverse environments beyond."  

The Voyager(TM) Compact Ultrasound Imaging System is priced below $5,000, making it affordable for all clinical specialties, medical offices, clinics, medical residents, students,
rural communities and developing countries. Slayton claims, "This is a disruptive technology in a $4B market. Voyager(TM) has a cost/performance equation that will expand point-of-care imaging beyond the current market growth projections of 20% per year".  

The flexible product design, combined with the power of the PC platform enables end users to continually increase the capabilities of the system by adding software/firmware upgrades, such as 3D and other options. Products are DICOM compatible for data transmission and archiving across networks, further supporting a broad range of care settings and clinical applications.  Novel mechanical, electronic and software designs insure exceptional reliability and performance. The company is working to establish an effective reseller network in the U.S. and international markets.

Ardent Sound, Inc. expects to receive FDA approval for two additional peripheral ultrasound imaging systems soon, including the Spark(TM) High Frequency Imaging System and Seeker(TM) General Purpose Imaging System. 

 Founded in Arizona in 1994, Ardent Sound, Inc. was previously known as Guided Therapy Systems, Inc. The company was reorganized in 2004 and remains a leader in researching, developing, manufacturing, and marketing diagnostic ultrasound imaging products and technologies.
