Three-dimensional infrared scanning: an enhanced approach for spatial registration of probes for neuroimaging.

ABSTRACT:

Significance

Accurate spatial registration of probes (e.g., optodes and electrodes) for measurement of brain activity is a crucial aspect in many neuroimaging modalities. It may increase measurement precision and enable the transition from channel-based calculations to volumetric representations.

Aim

This technical note evaluates the efficacy of a commercially available infrared three-dimensional (3D) scanner under actual experimental (or clinical) conditions and provides guidelines for its use.

Method

We registered probe positions using an infrared 3D scanner and validated them against magnetic resonance imaging (MRI) scans on five volunteer participants.

Results

Our analysis showed that with standard cap fixation, the average Euclidean distance of probe posit
