| Abstract: | Synchrotron‐radiation computed tomography has been applied in many research fields. Here, PITRE (Phase‐sensitive X‐ray Image processing and Tomography REconstruction) and PITRE_BM (PITRE Batch Manager) are presented. PITRE supports phase retrieval for propagation‐based phase‐contrast imaging/tomography (PPCI/PPCT), extracts apparent absorption, refractive and scattering information of diffraction enhanced imaging (DEI), and allows parallel‐beam tomography reconstruction for conventional absorption CT data and for PPCT phase retrieved and DEI‐CT extracted information. PITRE_BM is a batch processing manager for PITRE: it executes a series of tasks, created viaPITRE, without manual intervention. Both PITRE and PITRE_BM are coded in Interactive Data Language (IDL), and have a user‐friendly graphical user interface. They are freeware and can run on Microsoft Windows systems via IDL Virtual Machine, which can be downloaded for free and does not require a license. The data‐processing principle and some examples of application will be presented. |
