Newswise — Stony Brook, NY, November 6, 2017 – While x-ray imaging has been used for medical diagnoses for more than a century, scientists have not been able to precisely describe how light moves within nontransparent scintillators – the key component in large area x-ray detectors. When excited by ionizating radiation, scintillators emit visible light that is used to form an image. For the first time, scientists at Stony Brook University have directly characterized the physics of how light propagates within scintillators used in medial flat panel detectors. Their findings, detailed in this paper, could be a significant step toward developing even more efficient x-ray detectors to improve medical imaging and diagnoses.
X-ray dose efficiency is critical to medical imaging, as x-rays can be harmful to patients and increase their cancer risk. The researchers also anticipate that by understanding the physics of how light moves within scintillators, newer x-ray detector technologies can be developed to push the limits of x-ray image quality.
The research team used the National Synchrotron Light Source II at Brookhaven National Laboratory to conduct the research that led to their findings. For more details about the research, see this article.

About Stony Brook University
Stony Brook University is going beyond the expectations of what today’s public universities can accomplish. Since its founding in 1957, this young university has grown to become a flagship as one of only four University Center campuses in the State University of New York (SUNY) system with more than 26,000 students and 2,600 faculty members, and 18 NCAA Division I athletic programs. Our faculty have earned numerous prestigious awards, including the Nobel Prize, Pulitzer Prize, Indianapolis Prize for animal conservation, Abel Prize and the inaugural Breakthrough Prize in Mathematics. The University offers students an elite education with an outstanding return on investment: U.S. News & World Report ranks Stony Brook among the top 50 public universities in the nation. Its membership in the Association of American Universities (AAU) places Stony Brook among the top 62 research institutions in North America. As part of the management team of Brookhaven National Laboratory, the University joins a prestigious group of universities that have a role in running federal R&D labs. Stony Brook University is a driving force in the region’s economy, generating nearly 60,000 jobs and an annual economic impact of more than $4.6 billion. Our state, country and world demand ambitious ideas, imaginative solutions and exceptional leadership to forge a better future for all. The students, alumni, researchers and faculty of Stony Brook University are prepared to meet this challenge.
