About Wojciech Zbijewski
Primary Academic Title
Associate Professor of Biomedical Engineering
Background
Dr. Wojtek Zbijewski is an Assistant Professor of biomedical engineering at the Johns Hopkins University School of Medicine.
Dr. Zbijewski is leading a research program that focuses on development algorithms and devices for quantitative imaging, in particular using x-ray radiography and Computed Tomography (CT). Examples of recent work include performance optimization of 2D and 3D imaging trajectories for novel robotic x-ray systems, new technologies for ultra-high resolution CT (x-ray detectors, imaging system design, and image formation algorithms), dual-energy techniques for orthopedic Cone Beam CT, and quantitative shape analysis in applications ranging from orthopedics to 3D microscopy of human tumor samples.
Dr. Zbijewski received his M.S. in physics from the University of Warsaw, Poland, and his Ph.D. at the Imaging Sciences Institute, University of Utrecht, The Netherlands. He is currently affiliated with the Carnegie Center for Surgical Innovation and the I-STAR Labs.
His background includes the development of statistical reconstruction algorithms for x-ray CT and scatter correction methods for cone-beam CT using accelerated Monte Carlo techniques. His experience includes industrial R&D, where his work involved the design of specialized cone-beam CT systems for image-guided surgery, ENT, and dental applications.
