Magnetic field gradient causes different magnetic fields at different positions and different Larmor frequencies. This frequency variation can be used to determine the location of different anatomical features during reconstruction of an image.

Question

Quizplus · Accepted Answer

The magnetic field gradient is a crucial component in MRI technology, as it allows for spatial encoding of the MRI signal. By varying the magnetic field at different locations, it induces different Larmor frequencies in the spins of nuclei in the body. This variation in frequency is used to map the precise location of these spins, enabling the reconstruction of detailed images of the body's internal structures.
