Geometrical properties of gradient coils.

Parameters	𝑋-gradient	𝑌-gradient	𝑍-gradient
1st layer -𝑍[m]	1.18	1.20	1.29
2nd layer -𝑍[m]	1.37	1.40	1.40
1st layer -𝑅[m]	0.31	0.32	0.33
2nd layer -𝑅[m]	0.36	0.37	0.39
DSV: 𝑟[m]×𝑧[m]	0.42×0.42	0.42×0.42	0.50×0.56

Note: 𝑍 denotes axial length and 𝑅 denotes the radius of the primary and secondary gradient coil layers. The DSV size is given as the region where the gradient field is uniform to 5% peak-peak and is expressed as diameter by length in meters.
