powerful new IP-based network based solution that would streamline the sharing, storage and management of video data captured in surgery. “People have had cameras in ORs for a while,” observes Dr Iain Hennessey, clinical director of innovation at Alder Hey Children’s Hospital. “But we wanted to do it in a much more systematic way, and that is why we realised a networked approach was much more powerful. Everything is so much cleaner to have data flowing back to a server and integrated with your electronic patient records.”
As Alder Hey sketched its initial plans to build a purpose-built new children’s hospital, senior clinical teams saw the opportunity to with a partner that understood the realities of handling large volumes of AV data in a mission-critical networked environment. Working closely with Alder Hey’s IT department and other selected technology partners, Sony proposed and implemented a hospital-wide IP networking solution, allowing digital data from any source to be routed instantly to any destination.
A future-proofed networked video environment
Dr Simon Kenny outlines the parameters of the ambitious project: “In essence we wanted a standard system that applied across all our operating theatres. We wanted every OR to be networked and capable of performing the same tasks. Managing video has been difficult in the past because of different standards, formats and codecs – and every increase in bandwidth for clinical and diagnostic information ramps up data requirements. Sony has helped us implement a future-proofed, open source environment

that also lets us plan for future technologies and data requirements, like 4K.” IP encoder boxes in each of thirteen integrated operating rooms can be attached to any imaging device – including video feeds from visible light and other modalities like interventional radiology. Live video signals from an endoscope, room camera or other source can be displayed on LMD- 2760MD 27” LCD medical monitors. The ceiling-mounted monitors provide surgical staff a clear view of live video streamed from endoscopic cameras, operating light mounted camera or other imaging devices in the OR. Developed specifically for clinical applications, the LMD-2760MD features a Full HD resolution OptiContrast Panel that displays bright, detail-packed images from connected medical modalities with exceptional contrast and colour accuracy. Flexible operation is enhanced with a choice of picture modes, while the monitor’s intuitive ‘guided’ user interface assists simple fingertip operation. Digital interfaces simplify connection with a wide range of High Definition and Standard Definition imaging sources. Additionally, a wall-mounted 43” Bravia
Professional Display in each OR lets theatre staff see visual information from a wide range of sources. These include ceiling-mounted SRG-300SE PTZ remote cameras by Sony that capture an overview of the entire operating procedure with Full HD quality.
Live video captured during surgery can be patched instantly to monitor screens in another OR, consulting room or doctor’s office. Routing of signals across the hospital campus network is handled by NUCLeUS, a third-party video-over-IP-based platform that is driven by surgeons in each theatre via an intuitive touchscreen interface. “This is just like how a modern Soho post production house works,” says Dr Iain Hennessey. “We are not talking about video cables any more: it is all about moving data around the network over IP. Sony understands how to store and edit video, so we value taking these lessons and applying them to medicine and that’s a huge strength of this partnership.”
Helping surgeons focus
“The network has given us the ability to reach out from the OR,” states Dr Simon Kenny. “The days of a single surgeon making decisions in isolation are gone. We are always getting called to each other’s theatres to give advice. In the middle of an operation, your focus is 100% on the patient: that is when it is really useful to have an external opinion that isn’t coloured by your own emotions. Being able to see surgery on a screen elsewhere in the hospital is a great way to interact with other colleagues who have specific knowledge about a rare procedure.” As he points out, the networked screens play a significant role in optimising workflow in the OR: “Surgeon task performance is always enhanced by being aligned with the image. Having the moveable screens on the ceiling and being able to bring them into place really low where you are actually performing the task instantly gives us a massive performance boost. In terms of everyday application, this is as good as it gets right now.”
“It is vital that the rest of the team have an awareness about what is going on. If they don’t, risks like bleeding may not be appreciated by the rest of the team when the surgeon’s 100% focused on the task in hand. Letting everyone in theatre be able to see images from an endoscopic camera or an operating light mounted camera makes everyone immediately more invested in the case. When you can see it right there it is no longer an abstract thing.”
Networked imaging enhances medical teaching
As a leading teaching hospital, Alder Hey in the Park is also a focal point for specialist knowledge and pioneering techniques developed especially for the treatment and care of children and young people. Traditionally, the teaching of each new
