Crash test injuries analyzed with CT imaging provide valuable data that can help engineers develop safer cars and reduce the severity of injuries during car accidents, according to a new study by researchers from The Ohio State University in Columbus.
For the study, two human cadavers were hit with a device that simulates a blunt impact equivalent to car collisions. CT imaging of the rib cages of the cadavers was performed to evaluate the damage caused by the impact. "We found that injuries to the rib cage caused by the simulated car collision could be identified on the CT scans and that the CT results correlated with the usual, more involved methods of body damage analysis, which makes use of high speed videos and data from sensors attached to more than 30 locations on the body during the impact," said Steffen Sammet, MD, PhD, lead author of the study.
