Alternative Fan-beam Backprojection and Adjoint Operators
Patricio Guerrero, Matheus Bernardi, Eduardo X. Miqueles
We present in this work alternative analytic formulations for the fan-beam tomographic backprojection operation and its associated adjoint transform in standard (equiangular) and l…
Low-complexity Distributed Tomographic Backprojection for large datasets
Gilberto Martinez, Janito V. Ferreira Filho, Eduardo X. Miqueles
In this manuscript we present a fast GPU implementation for tomographic reconstruction of large datasets using data obtained at the Brazilian synchrotron light source. The algorith…
Phase-Retrieval as a Regularization Problem
Eduardo X. Miqueles, Nathaly L. Archilha, Marcelo R. Dos Anjos +2
It was recently shown that the phase retrieval imaging of a sample can be modeled as a simple convolution process. Sometimes, such a convolution depends on physical parameters of t…
Superiorization of Incremental Optimization Algorithms for Statistical Tomographic Image Reconstruction
Elias S. Helou, Marcelo V. W. Zibetti, Eduardo X. Miqueles
We propose the superiorization of incremental algorithms for tomographic image reconstruction. The resulting methods follow a better path in its way to finding the optimal solution…
Fast Backprojection Techniques for High Resolution Tomography
Nikolay Koshev, Elias S. Helou, Eduardo X. Miqueles
Fast image reconstruction techniques are becoming important with the increasing number of scientific cases in high resolution micro and nano tomography. The processing of the large…
