Stephen Rudin, PhD
Co-Director, Imaging Division
SUNY Distinguished Professor;
Director, Division of Radiation Physics
Education and research in medical imaging have been Dr. Rudin’s main interests during his rich career at CSVRC. His research pursuits have primarily involved the development of improved medical imaging methods to increase resolution and lower dose. His projects to develop high spatial resolution detectors that allow for better guidance and treatments during minimally invasive endovascular procedures have culminated in systems that are now in clinics world-wide. Current work is focused on high speed image development.
Daniel R. Bednarek, PhD
Department of Radiology
A specialist in radiological imaging physics and radiation safety, Dr. Bednarek is board certified in Diagnostic, Therapeutic and Medical Nuclear Physics by the American Board of Radiology. His research focus is on region-of-interest imaging including development and evaluation of limited-field-of-view, high resolution and, recently, high-speed imaging detectors with specific application to neuroimaging. Recent work has focused on methods for determination of patient and staff radiation dose and development of a real-time dose-tracking system (DTS) for interventional fluoroscopic procedures that culminated in a licensed, FDA approved product with worldwide distribution.
Ciprian N. Ionita, PhD
Co-Director, Engineering Division
Assistant Professor, Biomedical Engineering
Within the scientific community, Dr. Ionita has become deeply involved with the effort to implement the new advances of 3D printing into a clinical setting. Using his experience in CT reconstruction algorithms and 3D data analysis, he has developed a complex 3D printed vascular patient specific phantom, based on 3D imaging. Current work includes development of a DICOM standard associated with the workflow and manufacturing of 3D printed medical objects, developing implantable devices, and improving printed models by creating digital structures capable of simulating vascular tissue.
Swetadri Vasan Setlur Nagesh, PhD
Dr. Nagesh’s current work focuses on further improving quality of treatment by
proving superior imaging solutions are possible at lower x-ray doses. By using his novel artificial intelligence based image processing techniques, image quality can actually be restored in lower dose images. These images can then be used during interventions without compromising the safety of the procedure. Additionally, Dr. Nagesh collaborates closely with Dr. Rudin on the development of the new, 1,000 frames per second, high speed angiography project to image blood flow patterns in real time during interventions. The resulting flow pattern details provide critical information that aid in treatment of a variety of diseases and offer never before seen views into treatment outcome.
Vincent Tutino, PhD
There are several ongoing projects in Dr. Tutino’s lab that are focused on addressing clinical challenges related to acute ischemic stroke. Using advanced 3D analysis software and deep learning, he is automatically analyzing patient CT imaging, and coupling it with histology to create better tools for physicians to diagnose and treat strokes. He is also using cutting-edge molecular techniques to develop biomarkers of stroke pathogenesis and outcomes based on RNA expression profiles in patients’ blood and thrombotic tissue. Furthermore, in collaboration with other mechanical engineers, he is leading an effort to numerically model stroke treatments in order to enable in silico treatment planning and device development/prototyping and testing.
Lee Chaves, PhD
Dr. Chaves graduated from the University of Minnesota with a BA in Physiology and and PhD in Comparative Molecular Bioscience. His interdisciplinary doctoral program was focused on molecular biology, genetics and immunology. He completed a postdoctoral fellowship in immunology at the National Jewish Health in Denver and a second fellowship in immunology and nephrology at the University of Chicago. Dr. Chaves is currently using genome engineering (CRISPR/dCas9 techniques) to study genomic regulation associated with intracranial aneurysm. His enjoys collaborating with the diverse faculty and students and here at the Canon Stroke & Vascular Research Center.
