The code is in use or planned to be so at most US synchrotron facilities. Performance tests with up to 32, computing cores demonstrate that TomoPy provides highly scalable iterative tomographic reconstruction. TomoPy is installed and used in production mode at the Advanced Photon Source APS imaging beamlines 2-BM and ID and it is distributed to all beamline users to enable tomographic reconstruction at their home institution.

A Phatak C, Gursoy D Tomographic reconstruction creates three-dimensional views of an object by combining two-dimensional images taken from multiple directions, for example in how a CAT computer-aided tomography scanner allows 3D views of the heart or brain.

With synchrotron radiation, it becomes possible to obtain high-resolution density images, but also by analyzing x-rays emitted from fluorescence tomographs can show chemical information, by measuring the abundance of key elements. Data collection can be rapid, but the required computations are massive. Further, many common experimental perturbations can degrade the quality of tomographs, unless corrections are applied.

Unless automated tools make these corrections, beamline staff can be overwhelmed by data that can be collected far faster thancorrections and reconstruction can be performed.Released: Sep 28, View statistics for this project via Libraries.

A Feldkamp David Kress algorithm performs the reconstruction which have been adapted such that is exploits the axis-symmetric nature of the tomogram. This project aims at providing a simple, accessible toolkit for forward-projection and reconstruction of axis-symmetric tomograms based on a conical beam geometry. The toolkit is available via PIP, and the instructions below shows how a virtual environment can be created and the toolkit installed.

If you want to check out the examples, then download the files in the examples folder and run the examples. These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. Run the tests The tests should always be launched to check your installation. These tests are integration and unit tests.

Let us now go through the necessary steps for doing a reconstruction of a tomogram based on a single image. First, we need to import the tools. The dataset was collected during tensile testing of a polymer specimen.

Assuming that the example data from the repo is located in root folder, we can make a config object from the.

As we will use a single projection only in this reconstruction, we will reduce the noise content of the projection by employing a median filter. Using such a filter works fine since the density gradients within the specimen are relatively small. You may here choose any filter of your liking. Now, the axis of rotation has to be determined.

The axis of rotation is found by first binarizing of the image into object and background, and subsequently determining the centre of gravity of the object.

Contributions are what makes the open-source community such a fantastic place to learn, inspire, and create. Any contributions you make are greatly appreciated.

Please try enabling it if you encounter problems.The processing of tomographic synchrotron data requires advanced and efficient software to be able to produce accurate results in reasonable time.

In this paper, the integration of two software toolboxes, TomoPy and the ASTRA toolbox, which, together, provide a powerful framework for processing tomographic data, is presented. It is shown that both toolboxes can be easily installed and used together, requiring only minor changes to existing TomoPy scripts.

Furthermore, it is shown that the efficient GPU-based reconstruction methods of the ASTRA toolbox can significantly decrease the time needed to reconstruct large datasets, and that advanced reconstruction methods can improve reconstruction quality compared with TomoPy's standard reconstruction method.

In transmission X-ray tomography experiments performed at synchrotron facilities, large amounts of projection data are produced in a short time. Current detector technology allows one to collect projections at kHz frame rate, enabling three-dimensional imaging of dynamic systems Gibbs et al.

Processing these datasets in a time comparable with data collection is essential to properly capture the sample evolution and adjust the instrument settings during the experiment; this requires algorithms optimized for high-performance computing HPCwhich have to be easily available and usable by the beamline users.

By combining both toolboxes, we are able to leverage the advantages of both to create an improved workflow for beamline users. The TomoPy toolbox is specifically designed to be easy to use and deploy at a synchrotron facility beamline. It supports reading many common synchrotron data formats from disk De Carlo et al. TomoPy also includes several reconstruction algorithms, which can be run on multi-core workstations and large-scale computing facilities.

The algorithms in TomoPy are all CPU-based, however, which can make them prohibitively slow in the case of iterative methods, which are often required for advanced tomographic experiments. It includes advanced iterative methods and allows for very flexible scanning geometries. The ASTRA toolbox also includes building blocks which can be used to develop new reconstruction methods, allowing for easy and efficient implementation and modification of advanced reconstruction methods.

However, the toolbox is only focused on reconstruction, and does not include pre-processing or post-processing methods that are typically required for correctly processing synchrotron data.

The toolbox is available for Linux and OS X operating systems, and is aimed at providing a high-level interface for processing and tomographic reconstruction of datasets at synchrotron light sources. TomoPy relies on standard scientific packages like NumPy, SciPy and Scikit, and offers a free, open-source, modular, readable and manageable framework that researchers can use and contribute to easily. Python also offers easy integration with C or Fortran code through shared libraries in situations where computation speed is critical.

TomoPy includes a plethora of processing functions from pre-processing to image reconstruction of synchrotron tomographic data. It includes ring removal algorithms, such as the generalized Titarenko's algorithm Miqueles et al. The estimation of the rotation center can be calculated using the image entropy calculation based method Donath et al.

A single-step X-ray phase-retrieval algorithm based on Paganin filtering is available for phase-contrast datasets Paganin et al.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
