  • Sparse Reconstruction (Ongoing) - Investigation of novel reconstruction methods for low-count emission imaging, and low-cost multi-pinhole SPECT systems.
  • Data-driven Motion Estimation in SPECT (Ongoing) – Patient motion estimation from SPECT projection data with little or no information from additional surrogate motion signals. Strategies investigated are 2D-3D Registration and combined optimization of motion and activity using maximum likelihood.  
  • Analytical and Iterative Fan-beam algorithms for SPECT – Investigated different strategies for attenuation correction in analytical reconstruction. Implemented a novel shift-variant resolution compensation method for better image quality within iterative reconstruction, and conducted an image quality comparison study at multiple count levels between Parallel and Fan-beam SPECT for brain perfusion imaging using Tc99m (HMPAO).
  •  Motion estimation - Separation of respiratory motion and patient body motion from a signal acquired using a motion-tracking system for correcting SPECT images. Methods include Total-variation based smoothing, SVD & Quaternion-based algorithms for estimation of motion.
