Fourier-Based Forward and Back-Projectors in Iterative Fan-Beam Tomographic Image Reconstruction
Fourier-based forward and back-projection methods have the potential to reduce computation demands in iterative tomographic image reconstruction. Interpolation errors are a limita...

Motion Compensated Fan-Beam Reconstruction for Nonrigid Transformation
We develop an approximate fan-beam algorithm to reconstruct an object with time-dependent nonrigid transformation such as the heart. The method is in the form of derivative backpro...

A Hierarchical Algorithm for Fast Backprojection in Helical Cone-Beam Tomography
Existing algorithms for exact helical cone beam (HCB) tomographic reconstruction involve a 3-D backprojection step, which dominates the the computational cost of the algorithm. We...

Fast hierarchical backprojection for helical cone-beam tomography
Existing algorithms for exact helical cone beam (HCB) tomographic reconstruction are computationally infeasible for clinical applications. Their computational cost is dominated by...
