The portable Infrascanner Model 2000 handheld, screening device uses NIR technology for screening patients suspected of traumatic supratentorial hematomas of greater than 3.5 mL in volume that are less than 2.5 cm from the brain surface. It then identifies patients who should have an immediate CT scan referral and/or neurosurgical intercession. It comes with sensor with optical detector and NIR diode eye safe laser, along with a cradle. The digitized detector signal is analyzed by an SBC in the sensor, which receives the information sent by the detector and then makes any necessary adjustments to provide optimum data.
