Reduced-Helium Magnets from Philips a Game-Changer in MRI Scanners
BlueSeal magnet technology at work in Philips scanner at Poole Hospital in UK
Maximizing image quality is a given in any new magnetic resonance
imaging scanner. Delivering that capability to the maximum
number of patients and doing it cost effectively, however,
depends on optimizing workflows and maximizing scanner uptime.
Many radiology departments are currently under extreme
pressure to perform more MRI scans on more patients, not only
due to the aging population but also to deal with the backlog of
cases resulting from the Covid-19 pandemic.
Enter the latest generation scanners from medical equipment
maker Philips, a global leader in health technology, with magnets
requiring drastically reduced volumes of liquid helium for cooling.
Introduced in 2018 and now operating in healthcare facilities
worldwide, the equipment is proving to be a game-changer,
much of it due to the company's BlueSeal magnet technology.
Helium is needed to cool the scanner's magnet to a low enough
temperature, typically around 4-degrees Kelvin which equals a
frosty -269 degrees CC or -452.47 degrees F, to achieve superconductivity
- the only way of getting enough electrical current to
flow in the magnet's coil to generate the high-strength magnetic
field needed. Under abnormal operating conditions, for example,
when the coil momentarily loses superconductivity, known as
a magnet quench, significant volumes of helium typically vent
from a conventional scanner, not only posing a risk to patients
and staff but also incurring the down-time costs associated with

helium replacement and interrupted workflows.
Helium is also a finite and increasingly expensive resource,
which once released into the atmosphere boils off into outer
space never to be seen again. A conventional MRI scanner typically
consumes around 1,500 liters of liquid helium a year, and
there are around 40,000 of them worldwide. No wonder that MR
imaging professionals welcome a future that is much less helium
intensive.
BlueSeal uses just 7 liters of liquid helium to cool the magnet
