The ISMRM Open Science Initiative for Perfusion Imaging (OSIPI) is an initiative of the ISMRM Perfusion Study Group, founded in 2019 after a membership survey, and with a mission to:
“promote the sharing of perfusion imaging software in order to eliminate the practice of duplicate development, improve the reproducibility of perfusion imaging research, and speed up the translation into tools for discovery science, drug development, and clinical practice”
This IVIM code collection code library is maintained by OSIPI Taskforce 2.4 (currently not available) and aims to collect, test and share open-source code related to intravoxel incoherent motion (IVIM) analysis of diffusion encoded MRI data to be used in research and software development. Code contributions can include any code related IVIM analysis (denoising, motion correction, model fitting, etc.), but at an initial phase, development of tests and other features of the repository will predominantly focus on fitting algorithms. A future goal of the IVIM OSIPI task force is to develop a fully tested and harmonized code library, building upon the contributions obtained through this initiative.
If you would like to get involve in OSIPI and work within the task force, please email the contacts listed on our website.
If you would like to contribute with code, please follow the instructions below:
- Setting up Git
- How to create a copy of the respository and contribute changes to the repository
- Guidelines for IVIM code contribution
- Guidelines to creating a test file
The repository is organized in four main folders along with configuration files for automated testing.
The doc folder contains all documentation related to the repository of task force 2.4.
The src folder contains source code contributed by the the community. Within src, the original folder contains the code to be tested, and the wrappers folder contains code for harmizing the calls the different code contributions. Within the original folders, contributions are stored in Initials_Institution, e.g. src/original/OGC_AmsterdamUMC.
The test folder contains the test files corresponding to the contributed code in src. to be structured
The utils folder contains various helpful tools.
