The Infrascanner™ can be a practical solution to the problem of early identification of intracranial hematomas because of the unique light-absorbing properties of hemoglobin and the non-invasive, non-ionizing nature of NIR technology. The basic method for Hematoma detection is based on the differential light absorption of the injured vs. the non-injured part of brain. Under normal circumstances, the brain's absorption should be symmetrical. When additional underlying extra vascular blood is present due to internal bleeding, there is a greater local concentration of hemoglobin and consequently the absorbance of the light is greater while the reflected component is commensurately less. This differential can be detected via sources and detectors placed on symmetrical lobes of the skull. The science of diffused optical tomography used by the Infrascanner ™ enables the conversion of light differential data into interpretative scientific results. The Infrascanner ™ unit is a small, portable handheld device based on a PDA platform with wireless detector probes.
