Shaping the future of


The FieldLine HEDscan system is a non-invasive, wearable magnetoencephalography (MEG) device based on our optically-pumped magnetometer (OPM) sensor technology. Small quantum sensors are placed directly on the head to record and map neural activity with high fidelity. Our light-weight, wearable HEDscan helmets can accommodate people of all ages and head sizes.

The HEDscan device can be used in any room of any medical facility, without the need for expensive building modifications.
