Near Infrared (NIR) Technology in Infrascanner
The basic method for intracranial hematomas detection with NIR spectroscopy is based on the differential light absorption associated with the injured versus the non-injured parts of brain.

The Infrascanner compares the left and right sides of the brain in four different areas. The NIRS sensor is placed successively in the left and right frontal, temporal, parietal, and occipital areas of the head and the absorbance of light at selected wavelengths is recorded.
- Patient measurement is completed within 2-3 minutes
- Detects hematomas greater than 3.5 cc in volume
- Detects hematomas up to 2.5 cm deep from the surface of the brain (or 3.5 cm from the skin surface)
- Accuracy: Duke University Global Neurosurgery and Neurology recently published the largest independent, U.S. based Infrascanner study to date with 500 TBI patients, including 104 of these with intracranial bleeds. For all bleeds within the detection capabilities of Infrascanner (bleeds of more than 3.5 mL), the sensitivity was 94% and the specificity 96%. In those patients who required surgical intervention, the device demonstrated 100% sensitivity.*
