Re: Resolution key to surgery success

AJ2X, if HDMI is being used in these OR video systems, there are issues with tranmission over copper HDMI cables beyond 30m. You are correct in that digital video signals such as HDMI will not have any loss of resoltuion over long distances. However since HDMI is digital, beyond 30m with copper HDMI cables there will be compatability issues with some HDMI equipment leading to complete loss of the video signal. 

There are some HDMI "boosters" that may add another 10m to the effective copper cable length, but optical HDMi cables are the best solution for longer cable lengths. Since there are explosive gases used in ORs, opitical HDMI cables also offer a safer way to transport HD video signals than with copper HDMI cables.

I'm surprised at the claims made here.  HD video in surgery typically is routed via digital formats -- HD-SDI or DVI for live video, and ethernet for stored stuff.  With digital video, there is no loss of resolution in the transmission from place to place -- that is a primary reason for using it.  Standard definition video is almost always analog (NTSC and PAL formats being the most common legacy types), and it can suffer some loss of resolution in long distance transmission, or in moving from device to device, if care is not taken.  But high definition video has been a digital format since its adoption, and it delivers full resolution all the time, up until complete loss of signal -- there is no degradation with distance.  While optical transmission has some advantages, and can have a nice high data rate, I see nothing compelling for most ORs in this device.

Given that more and more surgical procedures rely on imaging as a key navigational tool, this is a welcome development. Clarity of video and range of sight are instrumental in allowing surgeons to carry out these procedures with specialized instruments instead of a reliance on heavy cutting.
