Teaching and learning the principles of magnetic resonance
imaging (MRI) can be quite challenging. The basics, however, can
be collapsed to magnetization, excitation, resonance, and magnetic
decay - all of which are analogous to the wave mechanics of a
plucked guitar string. In this lecture I draw out the close similarity
between the two fields using a guitar interactively. We avoid
quantum mechanics of proton spins and yet clearly explain basic MR
pulse sequences for spatial encoding, and how Fourier methods lead
to a reconstructed image using an intuitive approach. At the
conclusion, the audience gets new insights into the power of MR
Imaging with the hidden "magic" revealed.
If I can get the physics department's musicians to join me,
we will end the session with a performance of the "MRI Blues”.
