[Intl_DxMedPhys] Siemens PET/CT shielding?

[Ryan Fisher]

Hello!

We’re in the process of building out a new PET/CT suite, which is going to include multiple uptake rooms immediately adjacent to the scanner room, with an existing CT on the other side of the uptake rooms. Blueprint snip below, and it’s a Siemens Trinion PET/CT with a Force in the other room, FWIW. I reached out to Siemens to see if they had any specs as far as ambient exposure rates to either scanner to prevent image quality issues and just got a generic:

which is not super helpful as the site’s Radiation Safety Officer.

I’m wondering if anyone has experience with shielding this kind of layout? Siemens is the one who provided the basic room layout, so presumably they’ve installed something similar before without issues and shielding to occupational limits in the area is sufficient to prevent any artifacts? I guess I’m just surprised they don’t have any kind of “exposure rate > XX will affect camera performance” specification and am a little nervous of finding that out the hard way after everything is built and installed.

Thanks!
Ryan
