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, engineering professor Jeffrey Fessler and his research group have collaborated with GE Healthcare to greatly reduce the amount of radiation required to produce the same high-quality image. This technology was originally introduced at UM Hospital in early 2012, and is now being used by many hospitals around the country.
ABOUT THE PROFESSOR: Jeffrey Fessler is a professor of Electrical Engineering and Computer Science and BioMedical Engineering departments 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.
