Well I know the basics, that there is a strong magnetic field and atoms line up in there and so on, but then how it will eventually turn out to be a picture, what kind of measurments are done there or what data is registered with what sensors that will then become a picture on the screen?

[This article](https://www.maximintegrated.com/en/design/technical-documents/tutorials/4/4681.html ) has an excellent discussion of the process. Circuitry generates a specifically shaped magnetic pulse waveform, and listens to the radio energy released when the atoms snap pack in reaction to the pulse. After that, is software that turns it into a picture. The raw data is a series of slices with several different waveforms pulsed through each.
