-Thank you, I wish to investigate further.  However, MY needs extend
-past 10 bits and I have a 12 bit minimum goal; with 14 being best and 
-16 being overkill.  The application is radiography and the contrast is poor.

Just a thought as this is radiography, do you have to use an area scan camera
others wanting high resolution have in past hooked up line scan cameras or 
similar sensors to high speed A/D cards.

Basically are you only grabbing a single frame? (i.e. no continuous video)

Is this a normal radiography slow event?

What is the update rate?

Email if you wish to discuss.
