Roman, some exceptions are the Xray systems I am using. They are quite capable of exposing conventional Xray film and have real time CCD digital focal plane arrays as well.
These systems have very small (micron and nanometer range) spot sizes and an extremely wide power range (up to 230KV). Notice the resolution in the ant picture I posted.
However, they are very expensive and very heavy ($500,000. and 2 tons).
