'Jedi' helmet, used with Cryogenic Magnetic Resonance Imaging Machine

To take MRI (Magnetic Resonance Imaging) scans of the brain, these helmets were worn by children and adults. The coils are aerials for picking up MRI signals. Naming them after the Jedi knights in Star Wars films encouraged children to put them on and not to be frightened. MRI builds up a picture of the human body by using high frequency radio waves known as NMR (Nuclear Magnetic Resonance). MRI does not expose the body to radiation or invasive surgery and it can image soft tissues more effectively than X-ray-based methods.

    Glossary: MRI

    Magnetic Resonance Imaging (MRI). A technique for producing high quality images of internal organs and tissues. MRI uses radio waves to achieve its results. It is particularly effective in detecting cancers.

    Glossary: NMR

    Nuclear magnetic resonance is a technique used to detect what chemicals make up a sample containing unknown materials, or proportions of material. The sample is exposed to radio waves, and the frequency of electromagnetic energy that the sample absorbs is recorded. Because different atoms absorb unique frequencies of radiation, it is possible to determine what sort of atoms are present in the sample. NMR is now known as Magnetic Resonance Imaging (MRI).
