Flashcards

Precession

The rotation of a spinning object around its axis of rotation due to the influence of an external torque. It's like a spinning top wobbling as it spins.

Precessional (Larmor) Frequency

The frequency at which a spinning object precesses, determined by the strength of the magnetic field and the object's gyromagnetic ratio. It's like the frequency of the wobble of a spinning top.

Resonance

The state where an object's precessional frequency matches the frequency of an external radio wave, resulting in energy absorption. It's like pushing a swing at the right time to make it go higher.

MR Signal

The signal emitted by nuclei that are aligned with the magnetic field and then stimulated to precess at the Larmor frequency. It's like the sound a spinning top makes.
