DESCRIPTION OF INTERESTS

-Our research interests include all aspects of medical radiological and health physics with emphasis on imaging. In interventional radiological imaging, we are developing rapid sequence detectors and methods for aiding vascular interventions. We are developing a very high resolution micro-angiographic detector for exact guidance of ever finer neurovascular minimally invasive (catheter-based) procedures. Also we are actively participating in the development of direct conversion flat panel digital radiographic imagers. Work in our group includes not only new image detectors but also the use of real-time (pipeline) image processing computers for rapid sequence acquisition and processing of image data. Other projects underway include: Region of Interest Fluoroscopy which was initiated by our group for optimization of exposure with image intensified fluoroscopic and digital radiographic systems; the development of a new mammographic high resolution imager; droplet tracking methods for vascular flow determination; cone-beam computed tomography including image intensifier distortion correction methods; the characterization of the sensitometric properties of x-ray image receptors; rapid scanning beam radiography for scatter and veiling glare decrease; developmentof methods for quality control in diagnostic radiology; the measurement and reduction of patient dose during radiographic procedures. The acquisition of over $3.6 million of modern digital angiographic equipment in the new Toshiba Stroke Research Center has allowed our group to develop a unique multidisciplinary approach to solving vascular problems. In addition to doctoral research we are able to provide a complete hospital physics experience to all our graduate students in the form of a medical physicsresidency with actual on-the-job training in one or more of the university affiliated hospitals where we have radiation safety and operational responsibilities. We offer graduate assistantships including tuition waivers and attractive stipend to all our students.
