WSU’s Larry Zeng placed third in the world in the Low-Dose CT Grand Challenge, a global contest to produce a clear CT scan using a very low dose of radiation. The contest attracted 103 teams from 26 countries and was sponsored by the National Institute of Biomedical Imaging and Bioengineering, the Mayo Clinic’s CT Clinical Innovation Center and the American Association of Physicists in Medicine (AAPM).

Zeng, an associate professor of electrical and computer engineering, created an algorithm that uses geometry to rapidly detect and remove image distortions common in CT scans. He was honored by international peers at the AAPM annual dinner in Washington, D.C.
