haven't you seen the revolving hand/wrist or revolving skull on their website... i think these are what you are referring too. i think these are the rudimentary images... i also think someone who attended RSNA stated the skull imagery was what was used at RSNA.
and note: in fluoro bones are black and on plain films bones are white... with fluoro systems you view bones in black and a white "background," but you can also negate the image... make them look like a plain film... by making the bone white and the "background" black... you can see the negating happen with watching the revolving hand/wrist when you watch...
to people who are used to viewing these things, one can interpolate what a foot/ankle will look like...
My question to you is why would GE have signed a non-disclosure agreement with Imaging3 if they believed the product was only capable of producing the pictures we've seen so far?
