Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in the body. It is used for detecting brain tumors, traumatic brain injury, infections, stroke, dementia and root causes of headache. 

An enormous amount of energy is required to create the magnetic fields for the imaging process. The heat load can change rapidly from 5 up to 80 kilowatts within minutes. Proper cooling is needed to enhance image performance and prevent disruptions during examination.
