A headset that sends and receives electromagnetic signals has been used to accurately identify oedemas and haematomas in brain trauma patients, possibly paving the way for fast and cheap diagnosis in rural areas.
A small trial was carried out of the Volumetric Electromagnetic Phase Shift Spectroscopy (VEPS) headset in a military hospital in Mexico, and was successful in picking up differences in the structure of the brain caused by the presence of excess fluid or blood (an oedema in the brain causes swelling due to excessive fluid flooding the tissue, while brain haematomas can occur in different pockets of the brain when blood accumulates there).
