Applications of enhanced High Efficiency Computed Tomography

with Optimized Recursions (eHECTOR

Implementation and Evaluation of eHECTOR Prototype at National Institutes of Health

Nonlinear Iterative Reconstruction Time: Approaching Filtered Backprojection (FBP) or FFT Methods

1. Reduce projection count, exposure time, and radiation level many-fold

2. Increase quantitative accuracy while reducing computing time by
one to two orders of magnitude,

reaching speeds near linear methods

3. Can use a-priori information

eHECTOR is the Solution to Highest Numerical and Quantum Efficiency in Tomography   [1]

using Highly Contractive Mappings, related to Near-Orthogonal Updates
for X-Ray, TEM, CS MRI, and other imaging modalities
