InfraScan - Model 2000 - Infrascanner

The Infrascanner handheld brain scanner unit includes a sensor and a cradle. The sensor includes an eye safe NIR diode laser and an optical detector. The light to and from the laser and detector are optically coupled to the patient’s head through two disposable light guides. The detector signal is digitized and analyzed by a single board computer (SBC) in the sensor. The SBC receives the data from the detector and automatically adjusts the settings to ensure good data quality. The data is further processed by the SBC and the traumatic brain bleeding diagnostic results are displayed on the screen.

The Infrascanner Model 2000

• Integrates processing, display and control functions within the handheld brain scanner.
• Has been ruggedized for improved durability – especially in remote locations and on the battlefield.
• Is versatile and its availability is enhanced by the ability to use regular AA batteries in addition to a rechargeable battery pack.

The handheld brain scanner is turned on by placing a disposable shield on the sensor and turned off by removing the disposable shield. The sensor can be powered either by a rechargeable NiMH battery pack or by four disposable AA batteries. The cradle is used to charge the rechargeable battery pack, if it is used in the sensor, and to copy the data from the sensor into a personal computer.

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: In patients with Epidural, Subdural and Intracerebral hematomas: Sensitivity = 88% / Specificity = 90.7%*
