X-Ray Tomographic Imaging is a foundational diagnostic tool that provides rapid, noninvasive visualization of internal structures, supporting the diagnosis and management of a wide range of medical conditions. Researchers at UBC leverage advanced X-ray technologies, including digital radiography, computed tomography (CT), and fluoroscopy, to optimize image quality and improve clinical decision-making. By integrating X-ray imaging with translational research and clinical practice, our investigators enhance patient care, develop innovative imaging protocols, and contribute to the advancement of evidence-based medicine.

Philipp Blanke
Primary Location: St. Paul’s Hospital
Dr. Philipp Blanke is an Associate Professor at the UBC Department of Radiology and Staff Radiologist at St. Paul’s Hospital, Vancouver. He is the Director of the Cardiac CT Core Lab at St. Paul’s Hospital, which supports clinical trials in the field of transcatheter heart valve replacement and repair in regard to CT imaging for screening and follow up. His major research interest are cardiac CT for planning and optimization of heart valve interventions with a focus on investigational devices. Dr. Blanke received his medical degree and residency training from the University of Freiburg, Germany. He was previously a staff radiologist at the University of Wuerzburg were he successfully underwent the German habilitations process (Dr. med. Dr. habil.). He completed a fellowship in Advanced Cardiac Imaging at UBC/St. Paul’s Hospital before joining as a staff physician.
Manraj Heran
Primary Location: BC Children’s Hospital and Vancouver General Hospital
Dr. Heran graduated from the University of British Columbia medical school in 1996. He completed his diagnostic radiology residency training at the University of British Columbia
program in 2001, and obtained his FRCPC in Diagnostic Radiology the same year. Having completed fellowships in Pediatric Radiology (BC Children’s Hospital, 2001), Vascular and Interventional Radiology (Vancouver General Hospital, 2002), as well as in Diagnostic Neuroradiology (Duke University Medical Center, 2003), he returned to a joint staff position between Vancouver General Hospital and BC Children’s Hospital in 2003. Now in his twenty third year on staff, Dr. Heran is Head of the Section of Interventional Neuroradiology at Vancouver General Hospital, and a pediatric interventional radiologist at British Columbia’s Children’s
Hospital. Dr. Heran is internationally recognized in both fields and has served as the President of the Society for Pediatric Interventional Radiology (SPIR) twice. With cross appointments in Neurology, Neurosurgery, Spine, and Pediatrics, he is heavily involved in all aspects of medical education and clinical research. Areas of specific interest include the diagnosis and management of vascular malformations, spinal intervention, traumatic brain injury, interventional neuroradiology (including acute stroke and other ischemic cerebrovascular disease), and orbital radiology and intervention.
