Researchers at the University of Michigan have developed a system that allows clinicians to “see” patient pain in real time. Consisting of augmented reality glasses for the clinician and a cap containing brain sensors for the patient, the system uses artificial intelligence to convert brain activity data into a pain signature visualization so that the clinician can assess pain levels.
This new technology aims to provide a visual depiction of brain activity associated with pain, as a way for clinicians to assess pain levels in their patients. Called CLARAi (clinical augmented reality and artificial intelligence), the system involves patients wearing a sensor-loaded cap, which measures changes in oxygenation and blood flow to assess brain activity in response to pain.
These data are then interpreted by an artificial intelligence system that can learn which brain signals are linked to the pain response. A clinician can view the results using augmented reality glasses, where red and blue dots indicate the location and intensity of the pain signal in a virtual brain.
