What keeps rebar in concrete slabs from being pulled into MRI machines over time?

In: Engineering

Answer 1

You don’t need to worry about the MRI machine pulling the rebar through the concrete, concrete is really strong. That said, as others have explained, you don’t use rebar to make an MRI room. Not because the MRI might move the rebar but because the rebar might make the MRI images blurry. That makes the images worthless and that’s the whole purpose of having the machine.
