Paper Abstract
A software system has been developed for high-performance Computed Tomography (CT) reconstruction, simulation
and other X-ray image processing tasks utilizing remote computer clusters optionally equipped with multiple Graphics
Processing Units (GPUs). The system has a streamlined Graphical User Interface for interaction with the cluster. Apart
from extensive functionality related to X-ray CT in plane-wave and cone-beam forms, the software includes multiple
functions for X-ray phase retrieval and simulation of phase-contrast imaging (propagation-based, analyzer crystal based
and Talbot interferometry). Other features include several methods for image deconvolution, simulation of various
phase-contrast microscopy modes (Zernike, Schlieren, Nomarski, dark-field, interferometry, etc.) and a large number of
conventional image processing operations (such as FFT, algebraic and geometrical transformations, pixel value
manipulations, simulated image noise, various filters, etc.). The architectural design of the system is described, as well as
the two-level parallelization of the most computationally-intensive modules utilizing both the multiple CPU cores and
multiple GPUs available in a local PC or a remote computer cluster. Finally, some results about the current system
performance are presented. This system can potentially serve as a basis for a flexible toolbox for X-ray image analysis
and simulation, that can efficiently utilize modern multi-processor hardware for advanced scientific computations.
