Q/A with Anthony Grgas, Senior Project Engineer
Have you ever commissioned a project involving an MRI replacement before? If so, what are the challenges with these types of projects that you have faced before and if not, what challenges are you expecting to possibly come across?
I have commissioned an MRI project before and there are many interesting aspects and challenges about them:
- All building materials within the MRI room must be ferromagnetic (for example-only aluminum lighting fixtures and stainless steel duct)
- The entire MRI is encased in a shell constructed out of copper sheets/plates to act as a faraday cage and block out radio noise that could interfere with the imaging process
- The supermagnet within an MRI magnet is usually filled with helium at cryogenic temperatures, that must be provided with a cryogenic venting system as an instantaneous means of venting (in case anything goes wrong with the magnet or magnet cooling system)
- The cooling is usually provided by a dedicated process chiller, with an emergency domestic water switchover for emergency cooling in case of chiller (or chilled water pump) failure
- All mechanical equipment must be on critical emergency power circuits
