  <dc:description>The gratopy (Graz accelerated tomographic projections for Python) toolbox is a Python3 software package for the efficient and high-quality computation of Radon transforms, fanbeam transforms as well as the associated backprojections. The included operators are based on pixel-driven projection methods which were shown to possess favorable approximation properties. The toolbox offers a powerful parallel OpenCL/GPU implementation which admits high execution speed and allows for seamless integration into PyOpenCL. Gratopy can efficiently be combined with other PyOpenCL code and is well-suited for the development of iterative tomographic reconstruction approaches, in particular, for those involving optimization algorithms.

Highlights


	Easy-to-use tomographic projection toolbox.
	High-quality 2D projection operators.
	Fast projection due to custom OpenCL/GPU implementation.
	Seamless integration into PyOpenCL.
	Basic iterative reconstruction schemes included (Landweber, CG, total variation).
	Comprehensive documentation, tests and example code.
