Gratopy 0.1
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.
