There are numerous ones available for medium-format cameras (read Hasselblad, etc.). They typically are VERY expensive, and require all sorts of support equipment. I believe one of the major problems is to sync the shutter and the CCD, thus resulting in the high costs.
One can do a search for Hasselblad 555ELD and Kodak DCS Pro Digital backs.
