NeuroLogica Corp's (Danvers, MA) CereTom scanner instantly generates images of the neck and head in minutes to help diagnose brain injuries and bleeding. It can also reveal injuries to the elbows, knees, and ankles. After the scan is completed, it can be wirelessly transmitted to a doctor for diagnosis.As a side note, the NFL formed a traumatic brain injury committee and announced earlier this year that it's planning on looking at the potential link between concussions and depression in players.
