[Intl_DxMedPhys] Siemens CTDI Tool & Flash Protocol Questions

[Gretchen Raterman Bell]

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.

Thanks as always,n R. Bell, M.S., DABR
