SQUIDs (Superconducting Quantum Interference Devices) are applied to clinical areas and basic medical science fields because of their potential for measuring a minute magnetic signal from the human body. Magnetoencephalogram, one of their applications, is used for the functional mapping of the brain cortex before surgery and the localization of focus of epilepsy. Recently, their applications to the early-stage detection of dementia, the localization of brain ischemia and the evaluation of development disorder of children are suggested.
