5/20/2025 We’re excited to announce the beta release of QuSpin’s newly updated localization analysis software for the Neuro-1 system. This builds upon previous builds with upgrades that mark a major step forward in usability and automation. What used to require manual tuning is now streamlined—just load your data, select a few sensors, and hit “Go.”… Read more »

Summary: The QuSpin HALO platform offers a turn-key solution for quickly and accurately determining the location, orientation, and calibration data for arrays of QuSpin’s Optically Pumped Magnetometers. This streamlined system provides a user-friendly approach to sensor localization (the first step in the co-registration process) for advanced bio-magnetic sensing applications.    Optically Pumped Magnetometers for bio-magnetic… Read more »

Summary: QuSpin Localization Software enables fast, accurate calculation of sensor locations and orientations.  This beta release is part of the QuSpin HALO product platform that provides a simple solution for registering sensor arrays to medical datasets.    The advent of highly sensitive “zero field magnetometers” (QuSpin’s QZFM sensor for example) has paved the way for exciting… Read more »

Introducing Neuro-1, a state-of-the-art, integrated optically pumped magnetometer (OPM) sensor system designed for high-channel density biomagnetic applications such as Magnetoencephalography (MEG). This all-in-one solution combines QZFM sensors, control electronics, data acquisition, and power supply into a streamlined, unified system. A key advance in Neuro-1 (N1) is the miniaturization and integration of sensor control electronics. Thanks… Read more »

The third-generation QZFM sensor (Gen-3) is now ready for release! This is an important milestone that marks the final step in our three-step process to develop mature zero-field OPM technology. The Gen-1 sensor (2016) was a technology demonstrator built to validate the underlying technology. The Gen-2 sensor (2019) was a miniaturized version that paved the… Read more »

Our current Gen-2 QZFM can sense y and z components of the magnetic field but not x. Because many applications can greatly benefit from a sensor that can detect all three components, we have developed a new triaxial variant. The triaxial variant has the same size, weight, power, and cost as the standard variant. The… Read more »

The Sir Peter Mansfield Imaging Centre, University of Nottingham have, in operation, the first 50 channel OPM-MEG array based upon QuSpin sensors. The system uses Gen-2 QZFM mounted on the scalp using a flexible (EEG-like) cap, to measure the magnetic fields generated by current flow through neuronal assemblies. In this way it offers direct and… Read more »

A number of groups, including us, are exploring what an OPM-based MEG system will look like in the future. The technology is evolving rapidly so it is difficult to make a prediction but an EEG cap-like solution does look promising in the short term. In the photo below we explore a prototype MEG cap with… Read more »

Magnetoencephalography (MEG) and other biomagnetic recordings are generally made inside a magnetically shielded room (MSR) to suppress environmental magnetic noise. Traditional MSRs built for superconducting MEG systems are very large (for example 3.9 x 2.9 x 2.3 m) and cost around $1M. Optical MEG systems, such as QZFM based MEG, can be very compact and do not require such… Read more »
