Infrascanner Clinical Applications
Application approved in USA Application approved internationally
Hospital & Intensive Care Monitoring
Bedside monitoring for patients undergoing observation for small or delayed hematomas and also for monitoring post-neurosurgery patients.
Neurosurgery patients can be monitored as often as necessary, at bedside, to provide early detection of changes in intracranial hematomas between CT scans thus decreasing the frequency of damaging, disruptive, and inconvenient CT monitoring. Additionally, since approximately 20% of trauma-related hematomas do not appear for more than 12 hours following an accident, Infrascanner can be used effectively as a bedside monitoring tool for hospital patients undergoing observation.
Screening tool for mass-casualty events.
Objective adjunct tool for expedited evacuation decision-making.
The Infrascanner has a very specific application in detecting Traumatic Brain Injury (TBI) on the battlefield and in routine military settings where timely triage is critical. Recognizing its battlefield potential, the United States Navy’s Office of Naval Research and the United States Marine Corps have invested significantly in Infrascanner’s development and have successfully field tested it. Early hematoma detection is life saving technology that also supports prioritized evacuation of injured military personnel. The USMC has now fully deployed Infrascanner at all its battalion aid stations.
Screening in Remote Areas
Rapid initial evaluation enables critical decisions on whether to leave a patient in a local hospital or evacuate to a trauma center.
Head trauma patients can now be diagnosed at the site of injury by first responders. Infrascanner can be used in remote villages, small towns, islands, mines, sport clubs, skiing sites, hospitals and other locations that lack convenient access to CT scanners or neurosurgeons.
Infrascanner can aid in the decision to evacuate injured athletes to a trauma center or observe locally.
The growing recognition of sports-related brain trauma creates an ideal application area for Infrascanner. In contact sports like football, rugby, soccer, boxing and others, Infrascanner can provide sideline accuracy and help aid in the decision to evacuate injured athletes to a trauma center.
Triage of small children (where Glasgow Coma Scale is not reliable).
Objective adjunct tool for a decision on further investigation for light trauma patients.
Fast triage of trauma patients by making the right decision on where to evacuate the injured.
Infrascanner is not a replacement for a CT scan. It is a simple, easy-to-use screening tool that can be used to identify high-risk patients, requiring prioritization for CT scanning and neurosurgical treatment.
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%*
