Cortivision has expanded their SPECTRUM system from a mobile and wearable fNIRS platform into a fully mobile and wearable DOT fNIRS solution!
They now deliver complete hardware and software functionality for diffuse optical tomography. As part of the Cortivision ecosystem, Spectrum DOT provides researchers with a comprehensive imaging tool, expanding scientists’ access to an integrated platform that supports advanced brain research with precision, flexibility, and ease of use.
Light intensity is heavily attenuated in tissue and falls off exponentially from the illumination point. The maximum achievable probing depth of NIRS is limited by the illumination strength – determined by the thermal damaging threshold – and the detection sensitivity. Imaging depth strongly depends on the tissue type and the application. Typical achievable transmission limits of NIRS are about 12 cm for breast tissue, and 6 cm on the arm or leg. For brain imaging, the probing depth of NIRS is about 3 cm.
Diffuse optical tomography is a low-resolution technique owing to the physics of light propagation in scattering media. Depending on the composition and size of the target tissue, the resolution is on the order of 5-10 mm.
The temporal resolution of an fNIRS device depends on its hardware as well as how its individual channels operate with respect to one another. Through time-multiplexing of the source firing, some systems can achieve anywhere between 3-25Hz depending on the optode montage. For a particular application, scan speed can be traded off against the desired coverage area (field-of-view) or source density (image resolution).
