Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Upon presentation to the casualty unit at MRRH or MMH and following each CT scan, the study team will approach the patient to scan the patient's cranium with the InfraScanner 2500™. If permission is granted, the study team member sequentially measures the optical absorption for each of the 8 quadrants of the scalp (frontal, temporal, parietal, and occipital bilaterally). The device is engineered such that the light emitter and receiver are spaced 4 cm apart, allowing the light's intensity to be measured between adjacent light guides. This entire procedure, including greeting and scanning the patient should take \<10 minutes. Subsequent CT scan(s) the patient receives determines the number of potential data collections.
The patient and/or representative may refuse a scan during any encounter, and as such, the scan will not be done. For each patient scanned with the InfraScanner 2500™ they will be de-identified with a subject number, with age, sex, gender, skin color, hair color, hair thickness, mechanism of injury, Glasgow Coma Scale score, and mean time elapsed between CT scan and near-infrared measurement. These data will be stored in de-identified form on the Research Electronic Data Capture (REDCap) database and/or Microsoft Excel on a secured network drive within the Department of Neurosurgery at Duke.
The collection period for each research subject concludes 30-days following his or her initial measurement with the InfraScanner 2500™, patient discharge, or patient death.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
InfraScanner 2500™
All patients entered into the trial will undergo at least one cranial scanning using the InfraScanner 2500™ upon arrival to the casualty unit at MRRH following CT. Patients will be scanned using the InfraScanner 2500™ following each subsequent CT as allowed by patient or representative. Patients will know the results of the CT but not the InfraScanner 2500™. The standard for comparison will be determined as follows. A CT result that is positive for hematoma will be considered a true positive and a CT result that is negative for hematoma will be considered a true negative. In cases where the results of the CT are negative for hematoma and the results of the InfraScanner 2500™ are positive consideration of further follow-up will be given on a case-by-case basis.
InfraScanner 2500™
The Infrascanner is a portable screening device that uses Near-Infrared (NIR) technology to screen patients for intracranial bleeding, identifying those who would most benefit from immediate referral to a CT scan and neurosurgical intervention.
