Magnetic
resonance imaging (MRI) machines are complicated devices that can experience a
range of malfunctions. While some malfunctions are relatively minor, others
call for immediate servicing by a trained technician. Common issues that
indicate a need for servicing include:
Low Helium Alerts
All MRI
machines with superconducting magnets must have a readily available supply of
liquid helium for cooling purposes. In many cases, alerts occur when someone
has simply forgotten to properly monitor the helium supply. However, in other
cases, an alert may occur as a result of excessive helium consumption caused by
a damaged or dysfunctional cooling system. In either case, the supply of
cooling liquid must be replenished. Cooling system damage calls for additional
servicing.
Loss of Power
Magnetic
resonance devices may shut down spontaneously and fail to boot up in the
aftermath of a lightning storm. In some cases, a simple resetting of your
breakers will resolve this issue. However, if this does not work, you may
require a full reset of the entire MRI power system.
Loss of Image Quality
Over time,
your machine may start to produce images marred by graininess, unusual lines or
other types of unwanted artifacts. This problem may indicate serious problems
with a scanner’s main systems. However, it more typically points to damage in
the removable coils used in image production. You can address this simpler
issue by sending the affected coils out for off-site servicing.
Heat Exchanger Errors
A heat
exchanger cools off the heat-generating components in an MRI scanner. If this
component fails, the scanner may turn off and refuse to operate until temperatures
fall to an acceptable level. Suspect your heat exchanger if its LCD panel will
not turn on when you have a sufficient supply of power.
A reputable
MRI servicing company can recommend specific steps to repair your ailing
machine, as well as steps you can take to keep it running in good operating
condition.
