BIS Seminar

Speaker: Joseph Webster Stayman
Associate Professor in Biomedical Engineering at Johns Hopkins University

Bio: Dr. Stayman is an Associate Professor in Biomedical Engineering at Johns Hopkins University. He has been conducting research on x-ray and tomographic systems for over 25 years. He leads research programs in medical imaging systems modeling, design, optimization, and evaluation. His interests include diagnostic and interventional imaging and the integration of patient-, task-, and device-specific information into imaging devices and workflows; as well as the development of sophisticated image reconstruction algorithms and acquisition strategies for high-performance on low-fidelity or sparse data.

Abstract: X-ray computed tomography is one of pillars of diagnostic and interventional imaging. However, in many ways, clinical systems have not significantly changed over the past few decades. This talk will present several approaches that permit additional flexibility and adaptation in data acquisition to deliver improved performance and/or capabilities. These approaches combine hardware modifications and advanced modeling and data processing. Topics include fluence-field modulation for patient- and task-specific scans, noncircular CT geometries, novel filtration methods for spectral imaging, and the modeling and reconstruction methods that enable these non-standard acquisition techniques.
