Rethinking MRI with
Quantum Technology

Faster, better, and more accessible

We provide the world's first optical quantum sensor for direct magnetic field measurement in MRI. Unlocking a new era of unmatched accuracy, efficiency, and global accessibility in advanced medical imaging

The Problem

MRI magnetic fields are inferred rather than directly measured, forcing conservative scan protocols, reducing image quality, and driving up time and cost.

The Breakthrough

EXAAQ sensors directly measure the magnetic field during MRI scanning, removing uncertainty at the source of image formation.

The Outcome

Direct field measurements enable shorter scans, enhanced image quality, and higher throughput.

Redefining MRI by Removing Uncertainty

EXAAQ – a new quantum sensing solution for MRI – aims to make MRI faster, more accurate, and ultimately more affordable, by directly measuring the magnetic field at the heart of image formation.

A Hidden Limitation at the Heart of MRI

Today's MRI systems are engineering marvels built on decades of physics, signal processing, and advanced hardware. But at the core lies a critical limitation: magnetic fields are inferred rather than measured directly. Consequently

  • Slow, conservative imaging protocols are forced
  • Regular calibrations are needed
  • Image quality is unstable and suboptimal

The EXAAQ Solution

The EXAAQ magnetometer is a novel quantum sensor that directly measures the magnetic field during MR imaging, with an accuracy better than one part in a million. Instead of relying on assumptions, EXAAQ aims to remove uncertainty at the source and eliminate guesswork from image formation. This will enable:

  • Much faster scans
  • More reliable and accurate images
  • Lower operational costs

EXAAQ is designed to integrate seamlessly into any existing MRI systems, and does not interfere with scanner operation.

Why it Matters

For Clinicians
Better images improve diagnostic confidence.

For Hospitals
Higher throughput and lower cost per scan improve cost-benefit outcomes.

For Healthcare Sectors
MRI becomes a viable option in more clinical pathways and more regions of the world. When diagnostics become faster, better, and more available, outcomes improve – at scale.

The Future of MRI: Our Vision

Our vision is simple: EXAAQ sensors become an integrated component in every future MRI system. The results are:

MRI scans are faster by design.
Image quality is always high.
MRI economics fundamentally change.


We want to unlock the full potential of MRI, by combining quantum science with medical imaging. Our technology will replace the current complex and suboptimal field inference systems with one elegant, measurement-based solution.
