FEATURE: MEDICAL AV HAIVISION ENABLES HOSPITAL TO SHARE REHABILITATION EXPERTISE
The Cliniques universitaires Saint-Luc hospital in Belgium was seeking a technology solution to transmit live surgical procedures from the operating rooms at its Louvain- en-Woluwe campus to a conference centre located 400m away. This campus would host visiting professionals and medical students who could learn from surgical procedures and interact with the surgeon in charge. Saint-Luc selected Haivision’s Hai1020 system equipped with Mako codecs, which supports bidirectional delivery of live HD video with an end-to-end latency of under 70ms. Integrated into the Haivision system, the Mako
recover. So, instead of the noisy cooling fans used in the general all-in-one consumer PCs, the JAO terminal dissipates heat via an internal heat sink and a cooling plate connected to the arm or medical cart. This allows the system to run virtually silently.”
CONSISTENT SERVICE Reliability is, of course, another vital requirement. “You can’t have a system which goes to the infamous blue screen of death part way through your heart valve repair, can you?” smiles Tim Brooksbank, chairman of electronics display equipment company Calibre UK. “We develop products specifically for the medical market,” he continues, “but they tend to be spinouts from technology we originally developed for pro AV. Sometimes, the reverse is true too; a medical product
H.264 codec is said to guarantee excellent image quality at bit rates of just 3-5Mbps. The hospital was also able to use its existing IP network to deliver point-to- point video without making any major new capital investments or hiring additional IT staff. Because the Hai1020
systems support dual streams, doctors in the conference room can view images from medical imaging sources while they watch the doctor performing the surgical procedure. In addition, Saint-Luc was able to extend its HD video delivery, transmitted over a dedicated internet link, to a second university campus located 27km away in
might spin out a pro-AV product. For example, our HQView400-series product started life as a medical AV scaler for telepresence and training AV racks. The very low latency demanded by the medical market was also ideal for live-event pro-AV use.” Polycom has also
developed its product line specifically for the healthcare market, and Graley sees a real opportunity for integrators. “Existing installations are being continuously updated across Europe, and there are plenty of new-build clinical sites in progress or in planning,” he says. “Although many countries have a requirement for framework agreements to cover the commercial supply of equipment to hospitals, medical AV is still a specialist area where the tender process can help highlight the expertise of the integrator. Customers are
Louvain-La-Neuve. Properly demonstrating certain procedures requires transmission of three or four real-time video streams simultaneously, allowing doctors watching the procedure in the conference room to view all of the medical images at the same time. The extremely low latency of the Haivision encoding technology enables visitors and surgeons to engage in discussions without distracting delays. As a result, visiting doctors get a true-to-life experience and receive immediate answers to any questions they may have for the operating surgeons.
very keen to work with the supplier who can understand their requirements and provide a quality solution, on time and on budget.” “Integrators are especially successful in certain ‘hot’ areas such as telemedicine, but there are other opportunities for them as well,” adds Haivision’s Pfeuffer. “Healthcare has similar requirements to the enterprise market. Integrators can get involved in other use cases by leveraging simple solutions into expanded ones; for instance, by setting up a conference room and linking it to other clinical departments, an integrator can propose as a next step a digital signage installation – another hot area in healthcare. Then, as a medical AV integrator, the integrator can use the fact that it is already ‘on site’ to sell additional products. This is appealing to hospitals that prefer to use a single partner for as many of their technology needs as possible. AV integrators can certainly differentiate themselves this way, but it requires them to have deep knowledge of the healthcare market and focus on the big picture.”
“Because of their
knowledge of the human factors of communication, integrators can create excellent experiences for those who work in healthcare facilities,” notes InfoComm’s Duffy Wilbert, “as well as those who are receiving medical treatment.” In many ways, the healthcare market for AV solutions is a microcosm of the wider AV market. It makes extensive use of videoconferencing, digital signage, enterprise communications, meeting room technologies, IPTV, entertainment systems and so on. But it is also a specialist market in terms of applications and standards – not to mention often challenging procurement processes. It is also true that AV solutions that can have a critical impact on patients – such as in an operating theatre, for example – will remain the province of specialist medical integrators. Where the market is certainly no different, however, is in its preference to deal with a single supplier who is prepared to understand the problem and propose an appropriate solution delivering an acceptable ROI – skills which the best
