Inside MRI: The Scanner, Explained from First Principles

Field notes

The homepage models MRI as a four-stage pipeline: an RF pulse excites protons, gradients encode position, receiver coils capture the returning signal, and a Fourier transform reconstructs the image. Its six-module curriculum progresses from spin and precession to pulse sequences, k-space, contrast weighting, safety, and clinical anatomy, with each module marked beginner, intermediate, or advanced. The project says it is in beta and offers one short lesson per week by email.
