freeing up resources and increasing productivity. The company’s offering extends well beyond that, however, to include specialist solutions for radiology, mammography and modality acquisition (capturing, storing and transmitting data and images of different types from different sources) into the integrated surgical suite. “Remote collaboration via video solutions means that specialist doctors and surgeons can use their time more effectively, without wasting it travelling between locations,” notes Andrew Graley, director, healthcare at Polycom. “Eliminating travel time means experienced doctors and surgeons can treat more patients and guide more students, overall improving patient outcomes.” “Haivision’s main focus in the healthcare market is to help organisations securely access and manage high- quality video content for remote clinical collaboration and education, which in turn helps improve workflow, efficiency and patient care,” says Pfeuffer. “For clinicians who are performing surgeries and interventional procedures, Haivision’s technology is improving access to important content. In the operating room, there is often a lot of video and graphical content being viewed and used in many ways. Haivision solutions bring efficiency to the surgical team and hospital operations. Our secure IP video systems are also used to control and monitor operating rooms from nurses’ stations and to connect
operating rooms, labs, and auditoriums for collaboration and learning.”
FORMATS, RESOLUTIONS, ASPECT RATIOS The ability to handle a wide range of video formats, resolutions and aspect ratios is critical for AV systems in healthcare environments – a point made by Bjorn Krylander, managing director of graphics and video company Datapath. “Our video capture cards
are used in a range of healthcare applications, and notably in operating rooms,” he says. “Not only does the card need to be able to adapt to a broad range of signal inputs, but it must also be able to switch between them very quickly. The link between camera and screen has to have minimal latency – which is a real strength for us. A surgeon relying on what he’s seeing on a monitor cannot afford any delay between what’s actually happening and what’s appearing on screen.” Krylander also notes the importance of very high resolution. “Our cards can capture up to 4K x 4K images,” he points out. “That might seem like overkill – but what it provides is the ability to deliver a broad range of aspect ratios in various heights and widths at resolutions high enough to be of value.”
Krylander notes the growth
in the requirement for AV systems to support endoscopy procedures – and he’s not the only one. “We are seeing three areas of use for AV solutions in the
EYE SURGERY MOVES INTO NEW DIMENSION WITH 3D SOLUTION FROM SONY
The Ocular Microsurgery Institute (IMO) in Barcelona, Spain is an ophthalmology clinic specialising in the treatment of ocular disease and vision correction. The IMOsurgical team needed a technology solution thatwould enable them to educate trainees in howto provide the highest quality ophthalmic care and to help them develop their operating techniques. Sony’s integral3Dsolution,
which includes two PMW- 10MDcameras, an LMD- 2451MT 3Dmonitor and an HVO-1000MD recorder, is used for operations at the
healthcare sector,” adds Sven Feldman of New Media AV, Blackmagic Design's distributor in Germany.” The first is OEM solutions for a wide variety of surgical applications: a big growth area has been endoscopic surgeries. Education is another important application. A third is the recording of medical treatments for staff development and training as well as for legal purposes.”
MAKING MORE ACCURATE DECISIONS Sony’s Brandt believes that OLED technology has a vital role to play in enabling surgeons to make more accurate decisions when diagnosing patients and assigning appropriate treatments.
AMX PROVIDES BACKBONE FOR ANATOMY STUDENTS
A collaborative venture between the University of Glasgow and the Royal College of Physicians and Surgeons of Glasgow, the new Clinical Anatomy Skills Centre is an outstanding facility designed to further establish the city as a world- leading centre for the training of healthcare professionals. Glasgow-based systems
integrator Mediascape was asked to design, supply and install the digital audio-video system, and chose AMX Enova technology to provide a technological backbone for the facility. The laboratory comprises 10 work stations, made up of

from the
IMOto deliver the highest quality images for the operating team and trainees. The PMW-10MDhigh- definition camera enables the team to see the best quality images, even in low light conditions. The LMD- 2451MT and the LMD- 4251TD monitors receive the signal trans mission directly
one teaching station and nine student stations. A HD camera on a MediLED arm located above the main teaching station captures the didactic demonstration, which is in turn displayed on the 10 Mitsubishi 42in Full HD screens installed above each of the teacher and student stations. This camera feed
can also be relayed into the overflow area in the adjacent Jeffray laboratory, allowing additional students to see and hear the proceedings via the dual projection system. Alternatively, the teacher can select the camera feed from any of the student stations and send it to all displays in the facility.
“Because OLED panels are self-luminous, have high contrast ratios, quick response times and are 10 times faster than standard LCD displays, surgeons around the world prefer the technology for its stability of colour imaging and high- quality contrast,” he says. Making a contribution to the quality and efficiency of healthcare can come in small ways. Take Amina’s Invisible Loudspeakers. “Because they can be plastered over, they can’t become hiding places for bugs such as MRSA,” says the company’s sales director Babs Moore, “and cleaning becomes a much easier task.” In the healthcare market as in other AV markets, innovation is the norm rather than the exception. Barco, for example, was recently asked to make its bedside systems earthquake- proof. Sony is seeing uptake of 3D. “The Ocular Microsurgery Institute of Barcelona has recently been using Sony’s 3D technology to enable it to educate trainees on how to provide the highest quality ophthalmic care and to help them develop their operating techniques,” notes Brandt. (See case study above.) Haivision’s technology is being used to reduce the bottlenecks that occur when radiologists are having to provide content quickly for a number of simultaneous procedures.

receives the PMW-10MD camera’s signal and records the operation inHDand Blu-ray, allowing the procedure to be streamedto individuals outside the operating theatre.
REAL, QUANTIFIABLE BENEFITS
The benefits of AV technology in healthcare are real and quantifiable. Karolinska University in Sweden is using Polycom videoconferencing equipment, not to directly treat patients, but to train surgeons. Experienced surgeons can mentor colleagues at other hospitals as they perform procedures, particularly endoscopic retrograde cholangiopancreatography (ERCP). The success rate of these has risen from 85% to 99%: endoscopists at the hospitals classified the teleguided mentoring as a crucial factor in the successful outcome in approximately half of the operations.
common characteristics. “In all healthcare applications, consistent image quality, reliable performance and optimised workflow are critical,” says Domogalla. “This is also true for all AV equipment used throughout the hospital.” Polycom’s Graley builds on this point. “In life or death situations time is of the essence,” he adds. “Therefore, IT solutions must be reliable and responsive to avoid downtime and ensure patient care is not negatively impacted.”
“Something that is less obvious, though,” he
continues, “is that security is of the utmost importance in
