The evaluation of MRSI data is complex because data files are encoded with vendor specific file formats and there is a lack of standardized tools for reconstruction. A standard way to describe raw MRSI data is necessary for the reconstruction of sequences utilizing parallel and non-Cartesian sampling strategies. In this work we are developing a vendor neutral data format to define MRSI sequences with arbitrary k-space trajectories that can be used by reconstruction software to understand the data acquisition scheme. This file format is XML-based and uses the ISMRMRD header as a basis for its scheme.
