[Intl_DxMedPhys] Digital mammo and EM interference

[xuandong zhao]

We had it earlier this year with two of the rooms in a new hospital but
neither hologic nor hospital could figured it out what caused the problem,
so with the two rooms that has the issue, one we have to vacant the room
and switch to another, and the other we moved the units from one corner to
the opposite corner.

Hologic did suspect that the (main) power cable runs through the ceiling of
the vacated room caused the problem but hospital can’t relocate the line to
prove it
