jMRUI is a software package for advanced time-domain analysis of magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI) data. Through a user-friendly graphical interface biomedical researchers and clinical radiologists can use state-of-the-art signal processing algorithms to analyse and quantify spectroscopic data: from a single spectrum to a full multidimensional MRSI dataset.
The software interfaces algorithms for frequency selective filtering of signals (e.g., removal of residual water), correction of eddy-current artifacts, Cadzow signal-to-noise enhancement, linear prediction, non-linear fitting (quantitation of metabolites), and many more, all of them working in the time-domain to overcome the problems arising from FFT-processed data.
Additionally, jMRUI has a modular design that facilitates the development of plugins to further extend the core capabilities of the software; for instance to interact with PACS servers, to classify spectra, to simulate metabolite basis sets, etc.
The current stable version is jMRUI 5.2 relased on 25th May 2015. This version requires 32-bits Java 1.6 or newer and runs on Microsoft Windows® XP/Vista/7/10 and GNU/Linux®, 32- and 64-bits.
The current beta version is jMRUI 6.0 beta relased on 10th February 2017. This version requires 32-bits Java 7 or newer and runs on Microsoft Windows® 7/8/10 and GNU/Linux®, 32- and 64-bits.
