Introducing spatial information into MR

This lecture covers the fundamentals of magnetic resonance imaging, focusing on the addition of spatial information. Starting with the basics of MR, it explains the role of the static magnetic field, RF field, and gradient field in creating spatial encoding. The creation of gradient fields for spatial positioning and slice-selection techniques are discussed, emphasizing the importance of on-resonance magnetization. The lecture also delves into the principles behind MRI scanner gradient magnets and the Lorentz-force effect, which contributes to the loud noise during MRI scans.
