Hi, group!  I had to type in a new name for the list!

I was wondering if anyone has successfully grabbed the images produced (or not produced?) when using the CTDI Tool on Siemens.  My group covers a site that isn't ACR accredited yet for pediatrics, but I believe they will at some point.

In addition, we have another site with a Somatom Drive (dual energy, two tubes) that has the capability of acquiring with what's called Flash mode.  I believe the unit is using both tubes to be able to up the pitch, which is 3 in some of the protocols developed at the site with apps.  When I used the CTDI tool on their Flash Ped Abd protocol, the expected mA displayed in QA->CTDITOOL program came in at about half of what I'd calculate using the eff mAs, t/rot, pitch.  I'm assuming this is because there's two tubes??  Does anyone have any good reading material on how exactly these Flash protocols work?  I'd like to understand it better.
