Angus Kingon, professor of entrepreneurship and engineering, and team member Ou Chen, associate professor of chemistry, will build upon research by Emeritus Professor Ted Morse that led to the development and patenting of a proof-of-concept novel x-ray scintillation detector, which has demonstrated both vastly improved resolution and a means of reducing the radiation dose rate. Their research will have implications for medical x-ray imaging, such as mammography, by lowering the x-ray dose and increasing the ability to detect abnormal features at an early stage.
