Zonare releases first upgrade to z.one ultrasound system
19 August 2005
Mountain View, Calif., USA. Four months after releasing its z.one
ultrasound system onto the market, Zonare Medical Systems, Inc., has
released its first major upgrade. The new release features advancements in
2D imaging, colour and power Doppler performance, Dual Screen imaging and
significant additions to network connectivity. One of the first commercial
upgrades was downloaded via the internet at Mercy Hospital in Chicago.
The z.one system is based on the company's proprietary Zone Sonography
technology, which it says gives high image quality on a flexible platform.
It can be converted from a cart-based system into a compact portable system
with the performance of substantially larger and more expensive units yet.
The Zone Sonography technology includes a fundamentally new approach to
data acquisition and image formation. The system acquires data quickly in
relatively few large zones rather than many narrow lines, allowing more
rapid image storage, processing and display. In conventional ultrasound
systems, each line is formed by summing together the contributions of all
the channels in the transducer. As soon as each line is formed, the original
channel data are discarded. The z.one system aggregates the original channel
data and stores this information in Channel Domain Memory. All of the echo
information is then utilized in Channel Domain processing to form the image
and to provide greater options for image post processing by retaining all of
the original raw data.
Experts at PRI believe this technology could lead to greater diagnostic
confidence. “Since we now are able to retain all the raw echo data, we could
realize enormous advances in reviewing ultrasound data and enhancing
diagnostic outcomes,” said Martin Masel, Director of Imaging for PRI. “Prior
to this, we haven’t been able to access all of this data because a portion
of the echo information is discarded when using conventional ultrasound.
Zone Sonography technology could provide the key to more accurate post
analysis and lead to greater diagnostic confidence. Coupled with the ability
to convert to a premium compact system, the z.one unit offers us both a
powerful economic and clinical value.”
Zonare began commercial shipments or the z.one system in the first
quarter of 2005. Numerous radiology, vascular, interventional, emergency,
and other medical imaging facilities have installed the system to date. "We
believe Zonare's singular focus on ultrasound and introduction of Zone
Sonography technology will result in a rapid succession of clinical
ultrasound advancements," said Donald Southard, president and CEO of Zonare.
"Releasing this significant upgrade in such a short time after our first
commercial shipments is testimony to the power of the z.one platform's
architecture. We are dedicated to bringing innovation back to ultrasound
combining significant clinical and workflow solutions with outstanding
economic value, protecting our customers' investment today and in the
