The Princess Grace Hospital
The hospital provides 103 beds for acute care, with a wide range of associated medical facilities, in the West End of London, near to Harley Street.
An extensively equipped new imaging centre has been created in the basement of the hospital. The centre includes a Computerised Tomography scanner, mammography rooms, changing room, and waiting areas.
Magnetic Resonance Imager
The centre's main diagnostic tool is a I.5 Tesla MRI scanner supplied by GE. MRIs operate using a very high magnetic field, and so nothing within the magnet room, including lights and cooling ductwork, can contain iron or steel. A cryogen, using liquid helium, keeps the electromagnet superconducting, but refrigeration plant and back-up water cooling are also needed.
The heaviest component of the MRI, the magnet, had to be carefully lowered into position through a lightwell.
The complex services for the advanced medical equipment were installed without interruption to normal working of the hospital.
The normal hospital systems, including medical gases, nurse call, telephones, data, hi-fi and fire alarm, as well as comfort cooling and ventilation, also run throughout the centre.
There are comfort cooling and ventilation for the users as well as the refrigeration plant needed for the medical equipment.
