The medical physics program at the University of Chicago is recognized internationally for its research excellence. Many of the investigators are leaders in their respective specialities. Also, because the departments are located in the Medical Center of the University, there is strong interaction between the clinical and research staff. Faculty with a primary interest in diagnostic imaging hold appointments in the Department of Radiology, whereas faculty with a primary interest in the physics of radiation therapy hold appointments in the Department of Radiation and Cellular Oncology.
In January of 2000, the Department of Radiology completed construction of a new Multi-Modality Imaging Research Center. This center provides over 14,000 square feet of new research space dedicated to advancing the role of imaging in medicine. The research space provides for image analysis labs, wet labs for contrast medium development, hot labs for radiopharmeceutical research, and various image acquisition laboratories. The image analysis labs enable research in computer-aided diagnosis in breast imaging, chest radiography, skeletal radiography, computed tomography, SPECT, PET, reconstruction techniques, and vascular imaging. Construction of the new center was partially funded by an NIH construction grant. The new center houses the Human Imaging Research Office, the Carl J. Vyborny Translational Laboratories for Breast Imaging Research (VyTL), the Kurt Rossmann Laboratories for Radiologic Image Research, the Frank Center for Image Analysis, the PET Center, and other image-based laboratories.
The committee on medical physics also includes an NIH-supported Center for the development of EPR imaging for in vivo physiology. This is a development center for a new magnetic resonance imaging technique using electron paramagnetic resonance (EPR) rather than nuclear magnetic resonance (NMR) as its basis. High resolution (sub-millimeter) images with quantitative sensitivity to oxygen concentrations, tissue pH, and body fluid diffusion constants are available using this technique.
These research centers, as well as the other resources of the radiology and radiation oncology departments, provided medical physics researchers at the University with access to a great many state-of-the-art facilities:
