Tesseral gradient coil for nuclear spin tomography device

摘要

A tesseral gradient coil for a nuclear spin tomography device has a hollow cylindrical internal vol. with cylinder axis in the Z direction of a cartesian coordinate system. The hollow vol. contains gradient coils for generating magnetic field gradients whereby each winding of each tesseral gradient coil contains two segments (5a-7b) lying in the azimuthal direction connected by conductors. One segment of each winding lies on a minimum possible radius (r1) and the other on a maximum possible radius (r2) wrt. the cylinder axis.
