Surgeon Performs World's First 4X HD Surgery

docinthemachine writes with word of some "research just presented at the 65th ASRM on 4K surgery. Using bleeding-edge Hollywood 4K cameras coupled to laparoscopes, surgery was performed in 4K, or 4X the resolution of HD. Since laparoscopy is performed while viewing on a video monitor, this is a huge advancement of resolution and clarity for the surgeon. It only took a million dollars of projectors to show it to the audience."

Only?!?

Red Camera not really 4K

[chiefscienceofficer]

By their own admission the Red camera is more like 2.8K - They use a 4K Beyer pattern sensor which produces much less resolution than the total number of horizontal elements. Images are at best comparable to those produced by standard video cameras using 2/3 inch prism optics. This has been scientifically proven by Kodak in extensive testing using standard image evaluation methodologies. The Sony projectors that were used while capable of 4K images only use a portion of the display area to produce HiDef (1920X1080) stereo images. So while portions of the program may have been presented in 4K the images were not by any stretch 4K if they were produced by the Red camera. The 3D portions were in HiDef if they used the Sony 4K projector for that portion of the presentation. As mentioned elsewhere, the realtime output of the red camera is less than 4K so the surgeon does not see a "4K" image as he is performing the surgery - he has to wait for the relatively lengthy post process to complete in order to see his pictures. Real 4K equipment does exist - they just weren't using it. They might have gotten quicker and higher quality results by using a 35mm film camera to record the operation - processing the film and scanning at 4K. It would have taken about as long as their post process and produced real 4K images.
