Papworth Hospital is the UK’s largest specialist cardiothoracic hospital. Papworth Hospital’s radiology service has a key role in the diagnosis of all cardiothoracic conditions. The service uses state-of-the-art imaging technology and facilities include a CT and MRI scanner. The Radiology Department images over 50,000 patients each year.
The magnet in the MRI scanner at Papworth is cooled with liquid helium. As helium turns to gas and expands rapidly at temperatures above -260° C the system requires a safety valve and quench pipe to ensure that in the unlikely event of the helium turning to gas it will be safely dispersed outside the building.
Medical Gases engineered and installed a quench pipe, designed to withstand extreme cold, to provide this safety measure.
