U-M researchers are working to create a sophisticated algorithm to create high-quality CT scans from a much lower dose of radiation. Currently, CT scans require a very high X-ray dose to create an image quality for doctors to examine a patient's organs. With this new computing algorithm, currently used only at U-M hospitals, engineering professor Jeffrey Fessler has greatly reduced the amount of radiation required to produce the same high-quality image. ABOUT THE PROFESSOR: Jeffrey Fessler (http://web.eecs.umich.edu/~fessler/) is a professor of Electrical Engineering and Computer Science (http://www.eecs.umich.edu/) department at the University of Michigan. His research interests include medical imaging, tomography, nonparametric estimation, and inverse problems, with current and past projects in X-ray CT, MRI, PET, SPECT, radiation therapy, and image registration.
