[Intl_DxMedPhys] Hologic EMI Interference

[Little, Kevin]

Hi Travis,

We wrote up our experience shielding a room that couldn’t be moved a few years ago: https://urldefense.com/v3/__https://aapm.onlinelibrary.wiley.com/doi/pdf/10.1002/acm2.12366__;!!KGKeukY!1A8hpQE3XQo3d-JZn_OurN9S1uLmyhehyrf7wcCZgDOmiTXHArKt5p1se-rIsauWN-16X9FCjIgzDzPnc1XST1yh9sdEguO-ElTAnHO4tDGea1c$ 

Also, the diagnostic listserv has (mostly) moved to a new server: https://lists.osu.edu/mailman/listinfo/intl_dxmedphys_wd_osu_list . If you’re not signed up on the new list, you might be missing out on some good discussions! I’m copying my reply to the new list as well.

Thanks,

I have a client ready to install a new Hologic unit in a reserved shell space next to their previously installed units.  Hologic has done their routine EMI interference testing and has discovered problematic frequencies in the floor near the doorway of the room.  Facilities management and the plans for the building show no unusual materials in the floor of this area, just slab on grade.  There are some large electrical panels near the room (separated by a hallway) but they are quite close to rooms 1 and 2 with no issues there (installed for several years now).

Does anyone have any suggestions or experience attempting to shield from this type of interference in the event it can’t be eliminated?  Hologic does have a list of common items that can cause issues, but no good suspects have been identified.

Thanks in advance.

Travis
