How do ferromagnetic detectors work? - ANSWER-
Ferromagnetic detectors "monitor" the surrounding
magnetic fields. When something ferromagnetic moves it
distorts the surrounding magnetic field, Ferromagnetic
detectors sense that change.
List 3 types of ferromagnetic detectors used in MRI -
ANSWER-Single pillar
(screener), hand held (not for full body screening), doorway
(less sensitive -
best for large metallic
objects)
Where should pillar ferromagnetic detectors be located? -
ANSWER-In zone 2 -
before
zone 3.
How should MR staff dress? - ANSWER-Ferromagnetic free
