Summary

Purpose: The purpose of this study is to evaluate stationary head CT (s-HCT) as a diagnostic tool in patients with known head trauma.

Participants: Participants will be 50 people who have had either a head trauma or a brain bleed and have undergone a head CT in the past 24 hours or who will undergo a CT scan of the head.

Procedures (methods): This investigation will be a single arm, prospective clinical trial. Participants will have one single visit, which will include the s-HCT scan. No follow-up is required. All images will be de-identified before inclusion within a reader study. The investigators will perform a reader study with physician readers comparing the acquired imaging s-HCT images and conventional head CT.

Conditions

  • Head Trauma

Interventions

DEVICE

Stationary Head CT (s-HCT)

The system consists of a total of three x-ray sources and nine x-ray detectors with an estimation of approximately 150 projection angles per slice, with less than a minute per slice reconstruction. Radiation dose will be configured as to not exceed that of a conventional head CT, or 2 mSv. The subjects will be positioned on a medical procedure table that will move the subject through the scanning system at the rate of roughly 1 cm per second, during which the necessary x-ray projections will be acquired. The head will be positioned in a carbon fiber head holder from a clinical CT scanner that is secured to the table.
