textabstractThe ASTRA Toolbox is a software toolbox that enables rapid development of GPU accelerated
tomography algorithms. It contains GPU implementations of forward and backprojection operations
for common scanning geometries, as well as a set of algorithms for iterative reconstruction. These
algorithms are currently limited to using a single GPU.
A drawback of iterative
reconstruction algorithms is that they are slow compared to classical
backprojection algorithms. As a result, using only a single GPU can result
in prohibitively long reconstruction times when working with large data volumes.
In this paper, we present an extension of the ASTRA Toolbox with implementations of forward
projection, backprojection and the SIRT algorithm that can be distributed over
multiple GPUs and multiple workstations to make processing larger data sets
with ASTRA feasible.
