The IceVespa module is a flexible add-in functor for the Siemens IceProgramF ICE pipeline for MRS data. Raw MRS data is sent to a Python-based Vespa-Analysis spectral processing node via an XML-RPC client/server. Graphical and tabular spectral analysis fitting results are returned to the ICE pipeline and saved in the standard DICOM workflow. Analysis executes in its own process. XML-RPC was chosen for inter-process communication for its simplicity and flexibility for relocating the processing node using standard HTTP protocols. Combining Python-based IceVespa inline with standard C++ ICE processing increases processing algorithm choice while maintaining clinical access to quantitative MRS measures.
