Abstract
In preceding chapters., we described the physics of MRI using a classical approach. We started by comparing the properties of a hydrogen nucleus with those of a more familiar object — a compass needle. This comparison was valid because a compass needle and a hydrogen nucleus share several properties: In the presence of a magnetic field, they both tend to align with the external field, absorb energy through the phenomenon of resonance, and subsequently re-emit this energy. Each oscillates at a frequency that is proportional to the strength of the magnetic field. In the case of the hydrogen nucleus, this oscillatory frequency is the resonant (or larmor) frequency.
