Professional Summary:
Ciprian N. Ionita, PhD, is Associate Professor in the Department of Biomedical Engineering at the University at Buffalo, with adjunct appointments in Radiology and Neurosurgery. He directs the Endovascular Device and Imaging Lab at the Canon Stroke and Vascular Research Center. His research focuses on quantitative imaging and image-guided treatment of neurovascular disease, with particular emphasis on angiographic analysis, computed tomography, patient-specific vascular models, and AI-based decision support for endovascular procedures.
His group develops methods to improve intraoperative assessment of intracranial aneurysm treatment, stroke severity, and cerebrovascular hemodynamics. This work integrates medical imaging, computational modeling, additive manufacturing, and device evaluation to build and validate quantitative tools that can be used in the angiography suite. The lab has also developed patient-specific neurovascular and cardiovascular phantoms for software validation, procedural simulation, and testing of endovascular devices.
A major current focus is translation of quantitative angiography and machine learning into clinically relevant tools for real-time procedural guidance. This includes NSF-supported work connected to QAS.AI on AI-enhanced angiographic systems for intracranial aneurysm treatment planning and outcome prediction. Dr. Ionita has also contributed to national efforts in standardization of medical 3D printing through the RSNA 3D Printing Special Interest Group.

- METHODS AND SYSTEMS FOR ASSESSING A VASCULATURE Methods and systems are provided for assessing a vasculature of an individual. In an embodiment of a method, one or more angiographic parametric imaging (API) maps of the vasculature are obtained, wherein each API map of the one or more API maps encodes a hemodynamic parameter. A state of the vasculature is determined using a machine-learning classifier applied to the one or more API maps. (2021)
- X-ray diagnostic apparatus and medical image processing method An X ray diagnostic apparatus includes an X ray tube generating X rays, a first detector detecting the X rays, at least one second detector arranged in front of a first detection surface of the first detector and including a second detection surface narrower than the first detection surface and indicator points provided on a rear surface of the second detection surface, a projection data generation unit generating first projection data based on an output from the first detector, and a positional shift detection unit detecting a positional shift of the second detector relative to the first detector in accordance with an imaging direction by using the first projection data and a predetermined positional relationship between the points and detection elements in the second detector.
