Ultrasound

 
Satisfying the demand for easy portability


Medical equipment manufacturers are improving the designs and functionality to meet clinical and operational challenges in the ever-increasing effort to improve diagnoses, advance healthcare and save more lives. Middle East Health looks at a six ultrasound units which offer both portability and high performance.

The wide applicability of ultrasound in areas such as radiology, abdominal medicine, obstetrics, vascular and cardiac medicine alongside the demand from clinicians for smaller, higher performing systems is leading a new wave in the development of ultrasound devices that are smaller and more portable enabling clinicians to easily transport the units between departments and even take them on the road.

Zonare – z.one

Zonare has developed the z.one convertible ultrasound system which provides the flexibility to instantly convert from a full-featured, cart-based system to a compact unit with high-resolution and full exam capabilities.

Zonare says that whether the clinician is dealing with a routine exam in radiology or a trauma case in the ER, z.one can be instantly adapted to changing patient and exam needs. The flexibility of the z.one platform is designed to provide clinical solutions for a wide variety of imaging needs in general imaging, obstetrics, gynaecology, vascular and other emerging ultrasound applications.

"We have developed a next generation ultrasound platform, based primarily on software technology, which provides the clinician with far greater flexibility than traditional ultrasound systems," said Donald Southard, president and CEO of Zonare Medical Systems.

"This architecture, coupled with our proprietary Zone Sonography technology, has allowed us to bring the first convertible ultrasound platform to the industry with high performance image quality at a significant price to value ratio."

Zonare claim that their revolutionary approach behind Zone Sonography will change the way clinicians look at medical ultrasound. With conventional ultrasound systems, information is obtained by sending and receiving hundreds of narrow "lines" to form an image. Zone Sonography, on the other hand, acquires imaging information in a relatively few large "zones".

By gathering these large amounts of data very quickly – in much the same way that a photographic flash blankets areas – many of the physical limitations which previously restricted ultrasound performance are no longer factors. Additionally, instead of handling image acquisition and processing in customdesigned hardware – as conventional ultrasound systems do – Zone Sonography is largely implemented in software, on both the front and the back ends.

That means the performance of a Zone Sonographybased system is not tied to the speed of sound propagation, but rather to processor speed – a much faster and ever-expanding technology. By combining these advances, Zone Sonography is revolutionising ultrasound, enablingpremium image quality in a portable system.

Edward Lyons, MD, professor of radiology, Obs- Gyn and anatomy, University of Manitoba Health Services Center, Winnipeg, Canada, said: "I believe the architecture behind Zone Sonography will add tremendous flexibility and value to the clinical environment. It provides the same image quality and functionality as the traditional 400- pound ultrasound cart system while remaining completely portable.

“This is a tremendous advantage for a wide variety of imaging departments." Peter Jabeck, administrative director, Diagnostic Imaging for Mercy Hospital and Medical Center in Chicago, US, said: “The main reason we bought the z.one system was for its flexibility, compact size and functionality.

Now we have the ability to use one system for several of our off-site facilities without having to transport a heavy system around. Add this benefit to the z.one system’s scanning capabilities, plus images that are comparable to more expensive systems, and we have a tremendous asset in providing excellent patient care.”

The HD11 brings 3D/4D imaging into the mainstream by delivering it on a platform that is relatively affordable. “It is not high end in terms of price, but is high end in terms of capability,” Walter van Kuijen, general manager multi-country region and vice president Philips Medical Systems, told Middle East Health earlier this year.

A suite of advanced imaging modes delivers diagnostic power, for complete exam protocols, with incredible system responsiveness. Data management capabilities allow flexible recording, archiving, editing and even exam reports with embedded images.

Performance features

The powerful HD11 platform enables clinicians to customise the system to suit their clinical environment, with options ranging from stress echo to panoramic imaging and contrast.

It also allows more clinicians to experience the growing clinical advantages of 3D/4D imaging as well as specialised requirements for breast, transesophageal, paediatric, vascular, musculoskeletal and more.

The unit enables a more detailed view of foetal heart valves and wall motion to aid in detecting anomalies during routine obstetrical exams. The HD11 system supports more than 20 transducers, including many from the Explora line, for flexibility in meeting most clinical needs.

Ergonomic features

- The control panel and monitor move up and down, supporting users of all heights and allowing them to alter scanning between standing and sitting positions.

- The rotating control panel and monitor, as well as logically grouped mode and measurement keys, enable users to position controls where they’re most accessible, reducing extended reaching that strains shoulders.

- Up to five available ports reduce bending to switch out transducers.

- Advanced circuitry helps keep users and patients more comfortable by promoting a quiet and cool scanning environment.

- The integrated footrest allows correct posture, reducing stress on the spine.
