A California university has developed technology that could change the way some brain injuries are diagnosed. The technology uses electromagnetic waves from wireless signals to detect brain swelling or bleeding by analyzing data. The technology has the potential to be a lower-cost, more portable method of determining when a person has a brain injury.
A device created for a study of the technology uses coils to transmit and receive electromagnetic signals, and a computer algorithm analyzes the data to determine whether a person has brain swelling or bleeding. The waves used with the device are comparable to standing in a room with a TV on.
Researchers tested the device on a small group of healthy adults and a group of patients with brain trauma at a military hospital in Mexico. The results were different for patients that were healthy and patients that had brain damage. Bleeding and swelling showed different results. The study findings matched the results from traditional CT scans performed on the patients.
Researchers say that the technology could be useful in countries that do not have easy access to advanced medical imaging. It could also be useful in remote areas that are far from hospitals.
For people who suffer brain trauma, easier access to diagnostic equipment could make a difference in their outcomes. Head injuries and brain damage do not always have immediate symptoms, but prompt treatment is critical. Finding out quickly whether a person has brain damage could help them get to a facility for treatment more quickly.
