and device control are all required, as are encoding for web transmission and videoconferencing and unified communication technologies.
LIFE CYCLE Purchasing contracts normally stipulate that all equipment must have a minimum of a five-year life cycle and support guarantee. The design and build programme for a hospital rebuild or renovation can be lengthy and equipment will be expected to last. Substituting any item in a critical medical system is not a viable or quick operation. This is particularly relevant to the graphics cards used in medical imaging systems: rapidly evolving imaging technology and processing power reduces the life cycle of normal graphics cards to as low as six months.

‘Cardiologists and other specialists
are turning to 4K display to achieve the
level of clarity that they desire’
Rob Moodey, Matrox
Graphics points out that graphics cards are, “of necessity, extremely high- performance devices. In order to achieve DICOM compliance or simulation they need to have a deep greyscale and colour processing depth and may be required to drive several cloned workstations at once. For precise DICOM calibration, up to 13-bit gamma LUTs are required. Other features such as digital luminance correction, field-of-view correction and image colour profiling greatly simplify integration and setup in third-party imaging applications.” 4K displays are also
attractive propositions to the medical imaging industry and likely to be one of the first volume applications for this resolution. Moodey adds: “Cardiologists and other specialists are turning to 4K
display to achieve the level of clarity that they desire which puts added demands on the graphic equipment.” Geert Carrein, vice
president of Barco Healthcare, points out the necessity for technical and software support of graphics cards. “The image quality requirements of modern medicine and the necessity to create stations with up to five monitors put considerable demands on the performance of graphics engines,” he says. “We have developed a strategic partnership with AMD for ongoing product support and to allow our modification of the source code to suit specific medical application; leading to features such as the ability to zoom in to large images to show 1:1 part- images.”
As other areas within medical establishments turn
to digital display technology for signage, queue control and general information systems, AV integrators are entering the sector to satisfy that demand. There is considerable opportunity to develop the personal relationships that can lead to opportunities in the more medically oriented areas of hospitals and clinical activity. The tools and devices available for them to achieve success are readily available and already within the extensive service portfolio of professional installers.

TRINITY COLLEGE IDUBLIN NVESTS IN HIGH-SPEC MEDICAL TRAINING FACILITY
After 300 years, the Trinity College Anatomy Department has made the step into the 21st century. Jones AV installed one of the most advanced medical training facilities in Europe: a large teaching theatre with 12 student workstations and one advanced tutor/demonstrator workstation. Each workstation is a fully functional small operating theatre environment featuring an operating table for donor bodies with operating theatre light, medical monitor and manoeuvrable HD camera and 42in wall monitors with HD SDI inputs for endoscopes, C-bows or ultrasound. High-definition DICOM- standard video recorders are linked to a central archive server, allowing storage of pictures and video studies

that can be accessed via a web interface, connected to the university network with active directory integration. The system is driven by
a Crestron control system, with touchpanels at each workstation. Two tutor iPads give complete wireless control override of all functions. The central tutor workstation also features a 42in touch overlay for live annotation, while a freely routable videoconferencing system enables connection to other video conference units, computer desktops and iPhone or Android devices for live teaching sessions. To complete the teaching
environment, the college also includes two video editing suites for the production of educational video, connected to a DVD burning robot.
