SAN FRANCISCO Joel Eriksson Ek Youth Jersey , Sept. 16 (Xinhua) -- Researchers at theUniversity of Washington (UW) are developing the first smartphoneapplication, or app, that is capable of detecting concussion andother traumatic brain injuries in the field.

The app, known as PupilScreen, can detect changes in a pupil'sresponse to light using a smartphone's video camera and deeplearning tools - a type of artificial intelligence - that canquantify changes imperceptible to the human eye.

As described in a paper presented this week at Ubicomp 2017 Zach Parise Youth Jersey ,PupilScreen can assess a patient's pupillary light reflex almost aswell as a pupilometer, an expensive and rarely used machine foundonly in hospitals.

It uses the smartphone's flash to stimulate the patient's eyesand the video camera to record a three-second video.

The video is processed using algorithms that can determine whichpixels belong to the pupil in each video frame and measure thechanges in pupil size across those frames.

In a small pilot study that combined 48 results from patientswith traumatic brain injury and from healthy people, clinicianswere able to diagnose the brain injuries with almost perfectaccuracy using the app's output alone.

The U.S. Centers for Disease Control and Prevention (CDC)estimates about half of the 3.8 million concussions per year in theUnited States from recreational sports injuries alone still goundiagnosed, putting millions of young players and adults at riskfor permanent cognitive deficits.

A broader clinical study later this year will put PupilScreen inthe hands of coaches, emergency medical technicians Mikko Koivu Youth Jersey , doctors andothers to gather more data on which pupillary responsecharacteristics are most helpful in determining ambiguous cases ofconcussion.

And the team of UW computer scientists, electrical engineers andmedical researchers hope to release a commercially availableversion of PupilScreen within two years.

"Having an objective measure that a coach or parent or anyone onthe sidelines of a game could use to screen for concussion wouldtruly be a game-changer," Shwetak Patel, a professor of ComputerScience & Engineering and of Electrical Engineering at the UW,said in a news release. Enditem
