Fast and flexible X-ray tomography using the ASTRA toolbox

TLDR

Object reconstruction from projection images is widely used, yet commercial software often fails for non‑standard protocols or advanced reconstruction methods. This article introduces the ASTRA Toolbox, an open‑source solution aimed at researchers across multiple tomographic fields. The toolbox offers highly efficient, flexible tools for tomographic projection and reconstruction. Its main features and several use cases are presented, demonstrating its capabilities.

Abstract

Object reconstruction from a series of projection images, such as in computed tomography (CT), is a popular tool in many different application fields. Existing commercial software typically provides sufficiently accurate and convenient-to-use reconstruction tools to the end-user. However, in applications where a non-standard acquisition protocol is used, or where advanced reconstruction methods are required, the standard software tools often are incapable of computing accurate reconstruction images. This article introduces the ASTRA Toolbox. Aimed at researchers across multiple tomographic application fields, the ASTRA Toolbox provides a highly efficient and highly flexible open source set of tools for tomographic projection and reconstruction. The main features of the ASTRA Toolbox are discussed and several use cases are presented.
