I agree with Hawk, you can really kick it Chess.

I forwarded the article to 2 of the Physicists I worked with at University of California San Diego before I retired this past August. They will take a look, we all were working in Diagnostic Imaging and that was my specialty as a Certified Cardiovascular Engineer...now my time is mine...

Best wishes and a Merry Christmas to you and all QMC Longs...
