Professional Summary:

Education and research in medical imaging have been Dr. Rudin’s main interests at UB. In his role as Director of the CAMPEP accredited UB Medical Physics Program he has been involved in the career development of many who have had successful careers in clinical, academic, governmental as well as industrial medical physics including some of our own current faculty. 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 for use in better guidance for the minimally invasive treatment of stroke patients during the deployment of interventional vascular devices have culminated in systems that are now in clinics world-wide. Present projects involve the vast improvement of temporal image resolution with angiographic sequences at high speeds up to 1000 frames per second where single photon counting imaging detectors are used. Other research has involved lowering patient dose by region of interest imaging where the location and equalization masks are determined using machine learning, the testing of imaging systems with patient-specific 3D printed vascular phantoms, and objective measurements of imaging system parameters. The caliber, significance, and innovation of the research are demonstrated by the numerous grants that have been received from the NIH and industrial sponsors.

Research Expertise:

Medical Imaging Physicist: Diagnostic and interventional neurovascular imaging and endovascular devices. We pursue studies in medical physics involving new methods for imaging with x-rays, gamma rays, ultrasound, radioisotopes, and magnetic resonance. As part of the multidisciplanary UB-Canon(Toshiba) Stroke Research Center, we are investigating new imaging detectors, exposure optimization methods, and means to evaluate and modulate 3D neuro-vascular flow using phantoms made by our 3D printer. These imaging methods will be used to aid in the development and application of new therapies our group is developing to replace neurovascular surgical procedures for treatment of pathologies such as aneurysms, stenoses, and malformations. New image-guided, minimally-invasive, catheter-based treatments involve the development of specialized stents, flow diverters, embolic material, filters, and other devices. We are developing high spatial and high temporal detectors including advance single counting photon imagers. Some if the imagine processing involves machine learning techniques for artifact and noise reduction. Additionally, we have quality assurance and radiation safety responsibilities and access to university teaching hospitals which provides a practical training ground for graduate students while they pursue post-graduate research.
