Spatial distribution of the gradient field at different positions
inside the gradient coil
The diagram shows the spatial distribution of the maximum magnitude values of the vec-
tor sum of the field components generated by each of the three gradient units simulta-
neously at positions on virtual cylinders coaxial with the patient axis with diameters of
0.2 m, 0.4 m, and 0.6 m.
The virtual cylinders have the same length as the gradient coil. In the cylinder axis direc-
tion the points have a separation of 0.02 m.
The area shaded in grey indicates the length of the gradient coil.
