What are all the different types of noises that an MRI makes when you’re getting a scan? And why is it different noises every few minutes?
In: Technology
Sounds are caused by vibrations in the air.
Different kinds of vibrations cause different sounds.
An MRI generates very intense magnetic fields using electric coils.
When the magnetic field is changed this causes physical forces to act on the actual MRI machine, making it move or vibrate.
When the machine moves out vibrates, the movement is transferred to the air and you sense it as sound.
The different sounds are caused by different kinds of vibrations, which in turn are caused by different fields being generated.
The MRI needs to constantly change the field in order to focus on different areas of the body, and different kinds of magnetic waves of pulses allow for different kinds of readings, or to detect different molecules.
