It combines accessibility, interactivity and technical flexibility, within an environment suitable for both education and research. Our tool provides MR sequence design and simulation as a service , with no local installation needed by the user; alternatively, the code is publicly available on GitHub, for users who wish to deploy the application on their own server. MRI simulation sequence design web service Full Text Additional Declarations No competing interests reported.
