QuSpin & Mansfield Imaging Centre Advance Neuroscience with Highly Sensitive
Magnetometers

QuSpin, a manufacturer of highly sensitive magnetometers that
are gaining popularity among neuroscientists, reports that it has
developed a three-axis variant that will bring new sensing capabilities to magnetoencephalography measurements. Meanwhile,
researchers at the University of Nottingham have used the
company's two-axis sensors to operate a whopping 50-channel
array, shown above.
"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," reported Vishal Shah,
QuSpin founder and chief scientist, in March.

Scan of an adult magnetocardiograph shows the three orthogonal
magnetic field components measured using a single triaxial sensor
The triaxial variant has the same size, weight, power and cost
as the standard variant. Its sensitivity is slightly lower but it can
be ideal for use as a reference sensor for MEG, for magnetocardiography other applications. Deliveries are expected to
begin in the May-June timeframe, said Shah.

that operates in low field environments. It is among the most
sensitive magnetic detectors with performance rivaling superconducting technologies, says QuSpin. The sensor head
operates at room temperature and fully integrates the laser with
other components, eliminating the complexities of fiber optics or
cryogenics. Each QZFM is self-calibrating and can simultaneously measure field components along two axes. The compact
electronics module with a dedicated microprocessor provides
all necessary functionality to simply operate the sensor with a
few clicks of the mouse.

QuSpin also makes a compact, high-sensitivity Total-Field Magnetometer (QTFM) which can operate in Earth's field and can
resolve minute field changes for applications such as magnetic
observatories and aboard small, mobile platforms.

QuSpin describes its optical magnetometers as the first noncryogenic alternative to superconducting magnetometers that
are extremely sensitive, easy to use and very flexible and can
take extreme field sensing from the lab to
the real world.

Centre has configured what it says is the first 50 channel OPM-
