AR AI model can objectively identify, locate pain in real time

Machine learning, combined with neuroimaging data, has the potential to objectively determine whether a patient is suffering pain and where it's located. Accurate pain assessment is critical to provide proper diagnosis and treatment, medical experts agree. However, it's difficult to quantify pain, and most assessments are subjective. Subjective assessments are inconsistent and can't be used when a patient can't communicate, such as during surgery. They're also of limited value in understanding the neurophysiological processes underlying different types of pain.
