One of the most sophisticated wearable high-density diffuse optical tomography (HD-DOT) systems in the world, LUMO fNIRS combines a small, modular design with high-resolution functional brain imaging.

LUMO fNIRS is based on separate hexagonal sensor tiles that contain integrated optics and electronics, as opposed to traditional fiber-optic assemblies. This architecture preserves research-grade imaging performance while enabling quick configuration, outstanding scalability, and noticeably increased participant comfort.

High-Density HD-DOT Imaging Performance

A typical whole-head LUMO configuration includes:

• Up to 162 dual-wavelength light sources

• Up to 216 silicon photodiode detectors

• More than 7,000 overlapping measurement channels

• Source-detector separations ranging from 10 mm to 70 mm

• Imaging speeds of up to 12.5 frames per second

• Integrated 6-axis inertial measurement units (IMUs) sampling motion at 100 Hz

• Tile weights of less than 6 grams each

These dense overlapping measurements provide substantially greater spatial information than conventional low-density fNIRS systems and enable HD-DOT reconstruction algorithms to generate cortical activation maps with spatial resolution approaching that of functional MRI for cortical imaging.

Modular and Scalable Headgear

• The modular headgear of the system can be expanded to full-head coverage by simply adding more sensor tiles or tailored to image particular cortical regions.

• Depending on the needs of the experiment, headgear can be further customized with various light guides, cut-outs, and mounting arrangements. It comes in a variety of configurations, such as headbands, adult caps, child caps, infant caps, and neonatal caps.

Advanced Engineering Features

• LUMO fNIRS incorporates numerous engineering features that improve data quality, including multidistance channel sampling for physiological noise removal, custom optical filtering to reduce ambient light interference, anti-light-piping sensor design, real-time data streaming through Lab Streaming Layer (LSL), and compatibility with three-dimensional digitization systems for accurate cortical co-registration.

Flexible Brain Imaging for Research

These capabilities allow researchers to perform high-quality, reproducible brain imaging in laboratory, clinical, and real-world environments while maintaining exceptional flexibility and participant comfort.
