A common raw data format is a prerequisite for sharing MR image reconstruction algorithms and code, and is a necessary component of reproducible research. Ideally, this common format would be vendor neutral, and would capture the data fields needed to describe the details of the MR experiment so as to permit image reconstruction from the raw data. We propose the ISMRM Raw Data (ISMRMRD) format, which is described by an XML schema and several C-style structs. We demonstrate an implementation using HDF5 files for storage, along with C++, Python, MATLAB, and JAVA libraries for reading and writing ISMRMRD files.
