Press Release

Random Walk Imaging (RWI) is pleased to announce that Mass General Brigham (MGB) has acquired the advanced patent portfolio on medical imaging developed and held by RWI for the past 15 years.

The intellectual property (IP) portfolio, now under MGB’s stewardship, comprises sophisticated MRI techniques and analyses. These methodologies, aimed at elucidating tissue microstructures, hold significant promise in enhancing the diagnostic precision for conditions like cancers and neurological disorders. 

It’s noteworthy that several leading global research institutions have integrated and adapted
these methods to meet contemporary demands in clinical research. At the core of the approach is the “multidimensional diffusion encoding principle,” which enhances specificity in MRI applications, impacting clinical research and patient care. The portfolio contains several exciting MRI technologies, such as b-tensor encoding for mapping microscopic anisotropy, Maxwell-compensated encoding for rapid and accurate b-tensor encoding, M-nulling methods for mapping diffusion in moving organs, filter-exchange imaging for mapping changes in membrane permeability, diffusion-relaxation methods for mapping both microstructure and chemical composition of the tissue, and quantification of the relative amount of water in the tissue microcapillary network for more precise mapping of blood volumes.

RWI was founded in 2008, focusing on adapting strategies from solid-state NMR spectroscopy and magnetic resonance of porous media to clinical MRI. The work generated multiple patents for MRI and software to analyze the new data. RWI will retain the rights to distribute the analysis software, dVIEWR.

This software package, designed to study multidimensional diffusion MRI data, offers a user-friendly interface. RWI and its academic collaborators at Lund University remains committed to supporting users utilizing multidimensional MRI methods. Contact RWI directly for more information.

Random Walk Imaging AB is developing a novel proprietary approach to diffusion MRI. RWI is commercializing dVIEWR powered by MICE Toolkit™ as a novel software solution for clinical researchers and radiologists to better visualize and analyze diffusion MRI data. The company’s software solutions introduce a level of specificity to diffusion MRI that is unprecedented and that has the potential to non-invasively differentiate pathologies affected by changes in tissue microstructure. Based in Lund, part of the Swedish-Danish cross-border region of Medicon Valley, RWI has a broad intellectual property portfolio and unique translational expertise in advanced diffusion NMR and MRI methods.
