Princess Grace Hospital, Baker St W1

The building works were carried out on behalf of Princess Grace Hospital and KHC Construction.​                                                                                                                                                                                                                                                                                           

The old MRI scanner was stripped bare and new electronics, plumbing & shell casing were installed also special non-magnetic lighting & anti-static vinyl flooring were fitted.                                                                                                                                                                                 

The magnetic coil was left untouch owing to its weight of 4 tons and the difficulty of moving it from the basement to the ground floor.                                                                                                                                                                                                                                  

The MRI scanner is very sensitive to radio waves and therefore the timber walls, ceiling & floor is lined in 2mm thick copper sheets and a 2nd metal stud wall is built around the 1st wall.                                                                                                                                          

A new MRI scannner door was fitted which prevents the leakages of radio waves into & out the scanner room which would interfere with the various medical equipment.                                                                                                                                                                          

During the 2 months of building works, approximately 2000 litres of liquefied helium was used to top up the scanner since it had to be switch off.                                                                                                                                                              

The liquefied helium is used to cool the superheated magnetic superconductor to a temperature of minus 269  degrees​ which stops it from overheating.
