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. </dc:description> <dc:identifier>https://zenodo.org/record/5235563</dc:identifier> <dc:identifier>10.5281/zenodo.5235563</dc:identifier> <dc:identifier>oai:zenodo.org:5235563</dc:identifier> <dc:relation>info:eu-repo/grantAgreement/FWF/Einzelprojekte/P+29192/</dc:relation> <dc:relation>info:eu-repo/grantAgreement/FWF/Doktoratskollegs+%28DKs%29/W+1244/</dc:relation> <dc:relation>url:https://github.com/kbredies/gratopy/tree/v0.1.0</dc:relation> <dc:relation>doi:10.5281/zenodo.5221442</dc:relation> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>https://opensource.org/licenses/GPL-3.0</dc:rights> <dc:subject>Radon transform</dc:subject> <dc:subject>fanbeam transform</dc:subject> <dc:subject>pixel-driven projection methods</dc:subject> <dc:subject>computed tomography</dc:subject> <dc:subject>image reconstruction</dc:subject> <dc:title>Gratopy 0.1</dc:title> <dc:type>info:eu-repo/semantics/other</dc:type> <dc:type>software</dc:type> </oai_dc:dc>
