New technology developed at the University of California, Berkeley, is using wireless signals to provide real-time, non-invasive diagnoses of brain swelling or bleeding. The device analyzes data from low energy electromagnetic waves that are similar to those used to transmit radio and mobile signals. The technology, described in the May 14 issue of the journal PLOS ONE, could potentially become a cost-effective tool for medical diagnostics and to triage injuries in areas where access to medical care, especially medical imaging, is limited.
