OPM Helmets Enable Naturalistic, Movement-Tolerant Brain Imaging
Optically pumped magnetometer sensors, mounted in a lightweight three-dimensional printed helmet that conforms to individual head shape, let patients move naturally during scanning rather than remaining perfectly still inside a fixed cryogenic dewar, a requirement conventional SQUID systems cannot relax without significant signal degradation. Cerca Magnetics and QuSpin have both commercialized helmet-based systems since 2022, targeting pediatric epilepsy centers and movement disorder research specifically, where the ability to scan a moving or actively behaving patient opens entirely new clinical and research applications SQUID systems structurally cannot address regardless of engineering refinement.
