"4K technology is the next step to improve images for surgical interventions," says John Herman, responsible for European marketing for surgical use of Sony Medical solutions, while it explains advances posed the ultra high definition in this environment.

Standard definition (SD) videos provided surgeons an image of 680 × 480 pixels, even though in the past eight years hospitals have gradually migrated to the high definition video (Full HD), which offers sharper images of 1.920 × 1.080 pixels.

As noted by John Herman, head of European marketing of surgical solutions of Sony Medical, "if we had asked a surgeon if you would be willing to go back and give up the HD, had responded with an emphatic no. I would have argued that the standard definition already does not comply with the requirements of standard of care and that it could even pose a risk to the patient".

Similarly, the head of Sony Medical ensures that surgeons will be ready to adopt ultra high definition 4K, "which provides a much sharper image, with a greater sense of depth, what surgeons means to differentiate better the blood vessels or other microscopic structures. It also gives them greater confidence in the diagnosis of what you are seeing, as well as his movements and surgical acts. The 4 K also offers an enhanced range of colors, that allows to reproduce realistic colors."

As with HD, the next generation of 4K images creates a video chain closed from the source to the end result. Thus, in the operating room, the video signal is generated in the endoscope camera, surgical microscope or camera installed on a robot arm on the table of operations for open surgery procedures.

"4K sources require the Quad of bandwidth to transmit the signal compared to HD. Standard video cables are not practical to transmit images 4K effectively, since four cables would be needed. To this end we have designed a new platform able to convert the video signal to IP format and transmit 4K content via a single cable", specifies Herman.

The content can send anywhere in the hospital through the LAN connection to share it or store it. To view the image, the data is converted back to a video format, and although it can be played in any HD or 4 K device, only you can see the resolution and the original sharpness on a 4 K monitor.

This integral chain is essential in the operating room, where there can be delays in the processing chain, and it is where Sony Medical brings the experience of your live broadcast Department. "The surgeon who works with an endoscopic camera has no latency in the image - points Herman-; otherwise, the movement of the hands of this while viewing the image would not be coordinated. Any visible delay would make that the surgeon could not carry out the operation".

Currently, Medical Sony is the only company in the sector of surgical images that provides all the links of the chain 4 K. "there is a lot of competition for monitors or surgical recorders in various segments - Herman continues, but in the 4K chain, from the acquisition of the image processing; from recording to the display, our proposal is unique, with a full 4 K workflow".

In this sense, the company has been pioneering the development of monitors 4K for medical use and a system of recording 4 k for surgery. "Now we have just launched a 4 K content management system, and soon we will present our system of 4 K video over IP," explains Herman at the time that remember that Sony is a world leader "in image and processing technology sensors of" images and many of the most commonly used endoscopes camera modules is ours".

One of the most prominent functions of Sony 4K System IP is an open architecture designed from the industry standards and without requirements of patent, which gives hospitals the flexibility to connect any device or monitor.

Gracias a la infraestructura necesaria para la conversión a Full HD, muchos hospitales están listos para compartir contenido desde un servidor o un sistema de gestión de contenidos (CMS). Además, la necesidad de contar con capacidades digitales en otras áreas del ámbito sanitario, como en sistemas de archivado, transmisión de imágenes (PACS) y registros electrónicos, significa que la mayoría de los hospitales cuenta con una infraestructura de TI estandarizada compatible con vídeo a través de IP.

Hay dos áreas en las que la conversión a 4K presenta desafíos que deben tenerse en cuenta para la planificación. Muchos hospitales ya tienen dificultades a la hora de planificar el almacenamiento de los archivos de vídeo en HD, y con 4K estos problemas irán a más, ya que pueden ser hasta cuatro veces más pesados que los archivos HD.

Gracias al formato XAVC-S de Sony, estos archivos 4K podrán reducirse a un factor de tres en función de los ajustes de calidad de la imagen, lo que supone un significativo ahorro en . costes derivados del almacenamiento y en el hardware necesario para la edición.

The next area is the own operating room. While HD images go through a video cable, fiber-optic cabling is a prerequisite so that 4K displays in real time the surgical procedure is performed, for you need experience and a special care.

Upgrading to 4K within the operating room offers new opportunities for surgeons to access more information when they need it; have the ability to share images from several sources, such as CT or IMR of PACS systems, histories of patients or preoperative data in a single 4K of large size monitor.

Rather than improve images for endoscopic surgery, Sony is working with companies to study the potential of 4K in microsurgery technology. Due to the work so precise that it is required in neurosurgery or ophthalmic surgery, surgeons spend too much time looking through a microscope. Modules of 4K camera technology is compact enough to integrate it within the microscope so that it generates a sharp image 4 k on a monitor 4K for surgery, rather than be looking through a binocular.
