ASTRA-toolbox工具箱

关于CT重建，如今已经有许多可用的开源工具箱来实现，这避免了花大量时间研究算法并重现，在实际应用中非常便捷。比如ASTRA工具箱，不仅涵盖二维、三维重建，可GPU加速，而且兼容MATLAB、Python以及Windows、Linux系统，适合各类应用场景。然而，网上关于该工具箱的介绍很少，所以在此做一些简单介绍，以便参考和回顾。一、官网与下载工具箱的官网为： The ASTRA Toolbox www.astra-toolbox.com/ 在Downloads模块即可下载最新版本的工具箱：下载之后，还需注意在不同环境下的配置不同，比如我安装的Windows下的Matlab环境，就至少需要配置Visual Studio 2015，且做GPU加速需要CUDA8.0，等等。这些都可以在Documentation-Installation instructions部分了解。二、工具箱学习 ASTRA工具箱提供大量案例，而且官网Documentation部分详细讲解了所有的调用方式。分别针对投影对象、投影光束、算法等，都有不同的工具来初始化、重建图像等，大概看懂案例即可熟

TomoPy is a Python package that provides a set of tools for tomographic data processing and analysis. It includes algorithms for data preprocessing, reconstruction, and visualization, as well as tools for data analysis and management. One of the key features of TomoPy is its ability to interface with various tomographic reconstruction algorithms, including those provided by the ASTRA toolbox. The ASTRA toolbox is a set of open-source tools for tomographic reconstruction that is widely used in the scientific community. It includes a variety of algorithms for both 2D and 3D reconstruction, including filtered backprojection, iterative reconstruction, and total variation regularization. The ASTRA toolbox is designed to be fast and scalable, making it suitable for a wide range of applications. TomoPy provides a simple interface for using the ASTRA toolbox algorithms for tomographic reconstruction. Users can easily switch between different algorithms and adjust various parameters to optimize their reconstruction results. In addition, TomoPy includes a number of tools for visualizing and analyzing the reconstructed data, making it a powerful tool for tomographic data processing and analysis.
