I didn't notice the kV in the original post - but I'd guess about 150 kVcp.

Also I'd guess that the 3 microREM is one of those massaged "magic numbers"
like EDE which looks good since it is so much lower than the entrance
exposure - which is the number I'd like to see.

But - I'd also guess that the beam is highly attenuated with a rare earth
filter and that an edge contrast algorthym is used to enhance the image.

And - to keep Melissa happy and for those with CCMAIL ......
