User reviews

Great teaching app!

Love this tool. Helpful for working through complex MR physics.

MRI Education app

Yeah I mean the app is honestly pretty great. You can design your rf and gradient pulses and see the effect on a user-defined proton grid? Pretty cool.

I’d really like to see the view be able to rotate when pressing with both fingers. I’m getting used to rotating with one, but it’s not as common elsewhere. I like how the Maps app does it.

The Spins menu and the return button are shifted to the left on my screen, I think they should be centered or extended.

Maybe dark mode would be cool? Overall though as far as the substance of the app goes, there’s really nothing to complain about. You could totally add some educational walk-through which explains the motivation for a clinician to choose a specific pulse sequence over another, and maybe include different tissues as well.
