Medical imaging research centers on improving the display and analysis of images collected with a wide array of methods, including traditional x-rays, CT, MRI, PET, and ultrasound, among others. Such images are used for diagnosis, treatment planning, guidance, and verification. The tremendous growth in the use and study of medical imaging continues. Similar growth in computing power interacts with advances in basic sciences and computing methods to drive these advances. Biostatisticans play key roles in the research. Collaboration with members of the departments of Radiology, Radiation Oncology, Neurosurgery, Psychiatry, Biomedical Engineering, and Computer Science involve study design, analysis, and sample size choice, as well as data reduction and representations. The research includes both large multicenter trials and small laboratory studies. The medical research focuses on improving image representation and processing, as well as improving display. Over seventy faculty, students and staff on the Carolina campus identify themselves as involved in the Medical Display and Analysis Group.
