Biography
Director, Cardiac Catheterization Research Laboratory
Technical Director, Cardiac Catheterization Laboratory
Michael Van Lysel received a bachelor of science degree in physics and a doctorate in medical physics from the University of Wisconsin-Madison. He joined the Division of Cardiovascular Medicine in 1985. He has appointments in the Departments of Medicine (CVM) and Medical Physics.
Van Lysel's professional interests include cardiac x-ray imaging in the catheterization laboratory and using computed tomography. He holds patents for controlling x-ray exposure levels during dual-energy subtraction imaging and for measuring blood iodine concentration during videodensitometric quantitation studies. He has been the principal investigator for five National Institutes of Health R01 awards.
His previous research included developing and implementing dual-energy digital subtraction angiography, a motion-immune digital subtraction technique, and videodensitometric quantitation of cardiac function using dual-energy DSA. Current research involves work with a novel scanning-beam digital x-ray imaging system for use in coronary angiography and fluoroscopically-guided interventional procedures. The system is designed to provide images with a quality equivalent to current x-ray systems while reducing x-ray exposure to patients and medical staff by up to 10 times. The scanning-beam system also has the ability to provide real-time 3D tracking of interventional catheters and devices, such as those used for EP RF catheter ablation procedures. A new research initiative involves the development of combined CT coronary angiography and myocardial perfusion imaging.
Van Lysel teaches The Physics of Diagnostic Radiology, a graduate-level course in the Department of Medical Physics. He received the Sylvia Sorkin Greenfield Award from the American Association of Physicists in Medicine (AAPM) for the best paper published in Medical Physics in 1993, and the 1995 Biomedical Engineering Achievement Award by the Association for the Advancement of Medical Instrumentation (AAMI) for his work on dual-energy digital subtraction angiography.
