In an Oct. 15 Record article about a grant awarded to Jeffrey F. Williamson, Ph.D., to develop imaging methods for the improvement of cervical cancer treatment, an editing error omitted information about two of his collaborators. Williamson is working with Donald L. Snyder, Ph.D., the Samuel E. Sachs Professor of Electrical Engineering and professor of radiology, and Joseph A. O'Sullivan, Ph.D., associate professor of electrical engineering, to refine a method Snyder and O'Sullivan developed to produce streak-free computed tomography (CT) images in the presence of the bulky metal applicators used for cervical cancer treatment. These images will help the researchers see the tissues to determine how much radiation reaches healthy and cancerous tissues. The method eventually could be used to image soft tissue structures in the presence of dental work, orthopedic prostheses and other metal objects that now compromise the accuracy of CT imaging.
