The NIH's National Institute of Biomedical Imaging and Bioengineering has mentioned the work of Dr. McCollough in its educational article about computed tomography.
Constructing tools for researchers
Cynthia McCollough, Mayo Clinic
The goal of this work is to develop resources that enable the research community to easily create and compare new approaches to reducing radiation dose of routine CT scans without compromising diagnostic accuracy. So far, this has entailed creating a library of raw data from patient CT scans that researchers can manipulate to test new approaches, and developing computer-based methods for evaluating new approaches, so that researchers don’t have to rely on radiologists, which can be costly and time consuming. Using these assets, researchers have demonstrated that there is considerable potential for radiation dose reduction in CT exams of the abdomen, which are among the highest dose CT exams in common clinical use.
