Toshiba Stroke Research Center (TSRC), University at Buffalo, SUNY

Research Assistant, February 2002 – October 2006 

  • Image processing: Pre-processing projection images, to remove reconstruction artifacts
  • Region of Interest (ROI) cone beam CT: Reconstructing x-ray projection images acquired with an ROI filter in the beam reduces dose to the patient, while producing reconstruction comparable to full field of view (FOV). Combining full FOV projection images acquired at low dose along with truncated projection acquired at higher dose and higher resolution, produces a good quality reconstruction
  • Optimization in biplane imaging: Determining the relative geometry between two DSA images of blood vessels by optimizing an objective function that maximizes the formation of the 3D vessel
  • Sinogram completion: Reducing truncation artifact in CT reconstruction by determining objects lying outside the FOV using apriori knowledge that every feature in the sinogram traces a sine curve
  • Segmentation and visualization: Segmenting and visualizing 3D CT data sets
