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."
nice e-peen.
720p ought to be enough for just about anybody.
What an unfortunate choice of words.

The reviews were stinky. Entirely too long and the plot seemingly went in circles.
Must have been more real than seeing it for yourself...

4x HD may be new for video imaging, but other medical imaging techniques have used higher resolutions forever. >HD monitors are quite common in medical applications, too.
Oh... not that kind of 4X? In that case, I'll pass.

This technology has the potential to allow doctors to perform hard operations (writer's cramp, wrenched ankle) with the ease of the anklebone's connected to the knee bone procedure.

Congrads to Red Cameras. The really amazing thing is they have a 28K chip coming out so 4K is fairly low res.
Why?!?

The linked article could only have been written by a surgeon with incoherent longings for stardom and filthy lucre.
This technology offers no increased assistance for surgeons. It really doesn't matter when you're that close in a laparoscopy. It's not like the structures you need to see are that small for most laparoscopic procedures. I would have been more impressed if they'd hooked this up for use in neurosurgery, eye surgery, vascular surgery, something where real resolution and delicacy is required.
Big MEH.
I just checked their screenshots on my 1280x1024 17" LCD and I'm really amazed at the picture quality that 4x HD can provide!
I was under the impression that 1080p resolution was just a hair lower than 2K resolution. So wouldn't 4K be roughly 2x HD res?
With Hollywood, 4K refers to the horizontal resolution. With HDTVs, 1080p means the vertical resolution of 1920x1080. Therefore, it is approximately twice the resolution in the X dimension.
Well, actually, it's around 3.5 HD, but it's the thought that counts.
This baby is awesome. I get to look at tons of displays for work and this one still takes the cake- it's made by Barco, is incredibly bright, has a built in calibration puck, comes with some decent software (ie, easily 'configured' for our purposes), and all around blows the socks off of everything on the market.
Don't mind the $16K price tag.
The diffuser used is so clean you could eat off it- none of that nasty subsurface artifacting that looks like dust on your screen (speckle). Just pure, rich, saturated colors that are accurately represented with no TFT structure to worry about.
Now, IBM had the T221 (http://en.wikipedia.org/wiki/IBM_T220/T221_LCD_monitors) which had a native resolution of 3840x2200- at 200ppi- so that your eyes could never make out the substructure of the pixels. Best of all the monitor had hardware interpolation- it could be used at 1/2x to basically present the user a clean screen with nothing to distract your eyes from. IBM did this back in 2000!
I don't think they were too eager to talk about the display device actually used during the surgery itself...words that it was a 40" Vizio 720p LCD (affectionately called "1K"), from a pre-Black Friday extreme deal (you got to save where you can).
This isn't as big a breakthrough as I first thought.
I thought it said "sturgeon".
Brain surgery - it's not rocket science!
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.
4K is roughly 4,000 pixels across, not 4X "HD", which is probably assuming HD to be defined as 1920X1080. 4x HD, if you multiply each dimension, would be 7680x4320, a lot higher. I did see a demo of an 8k system earlier this year at NAB, quite nice on a large screen. Downsampled to 4k on a smaller screen and it was jawdropping. now if overall you mean four times the data, then yes, because it's roughly x2 in each dimension in two dimensions.
We've always used the horizontal pixel resolution to define filmout resolutions for cinema. (2k, 4k, etc.) Consumer product manufacturers use the retarded "megapixels" number so it sounds larger and more impressive. (multiply width x height for total pixel count).
I'm impressed that the camera optics they rigged into the laproscopy procedure had enough fidelity to make a 4k image worthwhile from such a small imaging source.
The RED system is the current darling of high end 'indie' filmmakers, TV shows and commercial producers everywhere where 4k is desirable, while the Canon 5D Mk. II is being used extensively for 2k owing to its full frame, exceptionally sharp sensor combined with Canon's unbeatable lenses, despite the fact that it is primarily a still camera. Both were all over the place at NAB this year, and I have the 5D Mk. II myself. The tools are getting cheaper and better every year and a lot of the old names in broadcasting are fading away...

Surgery is a rather imprecise and hackish profession, even today. The more high resolution the pictures you can give to a surgeon, the more solid their repairs can be. Laparoscopy took surgeries that used to leave huge 4" incisions across peoples chests down to a surgery which leave you with a few bandaid-sized scratches. Internally, even scratches of those sizes still take too long to heal; the smaller and more well-defined the repair, the faster the healing times, the less time you spend in a hospital bed and not out living your life.
Surgeons are clamoring for this technology. For smaller laparoscopic instruments with broader angle and higher resolution views. For the ability to do more surgical procedures with smaller cuts and less bleeding.
Did anyone else here read the article and think another group of programmers was getting together for a demoscene competition?
We can now outsource surgery to India as well? "Oh, hold on, my internet connection got laggy. Oh, sorry, well, ya can't sue for malpractice from another country, can ya! "
The Sony SRXR220 has a lot of technology to prevent movie copying. The actual projector is only a small part of this.
It has:
-Enclosure Security System
-approved receipt of secured DCP content.
-Key security system
-remote monitoring allows content to remain secure
-Ethernet control to separate PC through secure TLS session
-Sony exclusive internal watermark system
-Lamp can be changed without having to enter secured area
-electronic operator key entry system
-multilevel security with operator roles
-security management.
How this is used in a digital movie theatre:
The movies are typically delivered on a HDD by a dedicated fleet of trucks operated by Dolby. The trucks have a secured cargo space similar to a bank transport. The Dolby employee carries the HDD to the secure area of the theatre together with the designated operator who opens the key lock to the room. The Dolby employee enters his credentials on the projector, ejects the old HDD, and inserts the new. The projector will print out a receipt of events, and both the movie theater operator and the Dolby employee signs the receipt, and keep a copy each. The truck leaves with the old movie.
There is no UPS "overnight delivery" or any third party touching this.

We use 4xHD projectors at work... we have four of them all projecting on a 3-walled 'room' with a roof. We use it to project CAD images as 3-D images and with some funky Dame Edna glasses, you see a 3D image in front of you and when you move your head, the view changes along with it. So imagine having a car, you can open the door, sit inside it etc ... really really cool!

The drives I've seen at theaters have big DHL stickers on them. Dolby would love to have a stranglehold on the delivery, but they do not appear to.
The procedure I described, was the one followed in a Cupertino theater last year. They told me this was the procedure in the Bay Area. I am curious if this has changed.
