Research Interest
Analytic methods image reconstruction from projections: Development of theory and algorithms for limited data problems in classical tomography, for example, region-of-interest reconstruction from truncated projections. Analysis of sufficient and insufficient data configurations and what object features can and can not be reliably reconstructed in these situations Dynamnic region-of-interest reconstruction: Development of theory and reconstruction algorithms for imaging non-static specimens with incomplete (e.g. truncated) data. A typical example would be scanning a patient throughout several respiratory cycles with a detector too small to cover the full transaxial extent. Geometric calibration of cone-beam scanners: Development of direct analytic methods of obtaining geometric parameters of a generic cone-beam scanner by imaging a known calibration phantom and extracting the scanner geometry from the measurements using direct formulas.
