The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Iterative reconstruction techniques in emission computed tomography (2006, methodology): “For example, exact FBP algorithms have now been developed for helical geometries (Katsevich 2002).”
Reconstructive Integral Geometry (2004, methodology): “Katsevich [49] has adapted Grangeat’s method for numerical implementation.”
Evaluation of Sparse-view Reconstruction from Flat-panel-detector Cone-beam CT (2010, methodology): “When the projection views are sparsely sampled, the analytic reconstruction algorithms (Feldkamp et al 1984, Katsevich 2002, Zou and Pan 2004, Pack et al 2005), which require densely sampled projection views, can result in prominent streak artifacts (Brooks et al 1979, Crawford and Kak 1979).”
A two-step Hilbert transform method for 2D image reconstruction (2004, methodology): “The new formulae were initially built on special cases of the cone-beam reconstruction method introduced by Katsevich (2002).”
