PITRE (Phase-sensitive x-ray Image processing and Tomography REconstruction) is a software developed by INFN Trieste n order to facilitate and standardize the simulation and elaboration of X-ray phase contrast images. The acronym PITRE in Italian is pronounced /'pi.tre/; the pronunciation is the same of “P3”, which is then chosen as a logo for the PITRE program. A batch processing manager for PITRE, called PITRE_BM, can execute a series of tasks ("jobs"), which is created via PITRE, without manual intervention.
PITRE is freeware and allows:
System requirements: nowadays PC can run PITRE without any problem. One suggestion is to have sufficient RAM size due to the sinogram generation method. Moreover, it is recommended to use 64-bit version (both for the OS and for PITRE) rather than 32-bit in case the PC RAM size is larger than 4 Gigabytes.
1. Install 32/64 bit IDL (version 7.1 or higher), which can be downloaded from Exelis Visual Information website after a simple registration, on windows XP (or newer version). The IDL Virtual Machine is included in the IDL installation file and does not require a license to run.
2. Download the PITRE installer (32/64 bit) and run it as Administrator; the installer will process the following actions on your PC:
3. Reboot the PC.
4. Double click `PITRE.sav` (or use IDL Virtual Machine to open it) to run the software.
