Infrascanner™ is a hand-held,
non-invasive, near-infrared (NIR) based
mobile imaging device to detect brain
hematoma at the site of injury within the
“golden hour”. This refers to the period
following head trauma when pre-hospital
analysis is needed to rapidly assess the
neurological condition of a victim. Pending
FDA clearance, the Infrascanner™ will
be an affordable, accurate and clinically
effective screening solution for head trauma
patients in settings where timely triage is
critical. It is intended to aid the decision
to proceed with other tests such as head
Computed Tomography (CT) scans. In
environments where access to CT scan is
restricted or not available, Infrascanner™
will facilitate surgical intervention
decisions.
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. |
