Propagation-based phase-contrast X-ray imaging is by now a well established imaging technique, which - as a full-field technique - is particularly useful for tomography applications. Since it can be implemented with synchrotron radiation and at laboratory micro-focus sources, it covers a wide range of applications. A limiting factor in its development has been the phase-retrieval step, which was often performed using methods with a limited regime of applicability, typically based on linearization. In this work, a much larger set of algorithms, which covers a wide range of cases (experimental parameters, objects and constraints), is compiled into a single toolbox - the HoloTomoToolbox - which is made publicly available. Importantly, the unified structure of the implemented phase-retrieval functions facilitates their use and performance test on different experimental data.

用于 X 射线全息术和断层扫描的相位检索工具箱。

基于传播的相衬 X 射线成像现已成为一种成熟的成像技术，作为一种全视场技术，对于断层扫描应用特别有用。由于它可以通过同步加速器辐射和实验室微焦源来实现，因此它涵盖了广泛的应用。其发展的一个限制因素是相位检索步骤，该步骤通常使用适用范围有限的方法来执行，通常基于线性化。在这项工作中，涵盖广泛案例（实验参数、对象和约束）的更大的算法集被编译成一个工具箱 - HoloTomoToolbox - 并公开提供。重要的是，所实现的相位检索函数的统一结构有利于它们在不同实验数据上的使用和性能测试。
