ABSTRACT:
A cylindrical whole body MRI z gradient coil having multiple windings which are individually wound about a cylindrical support structure such that the windings are evenly distributed in azimuthal angle and interleaved with one another. The windings are preferably spaced in azimuthal angle by 360.degree./N, where N is the number of windings. In such a design, there is no net gradient along any transverse direction and the homogeneity of the gradient field in the transverse direction is thereby improved due to the resultant cancellation in terms proportional to the transverse field gradients. The multiple windings may be selectively connected in series or parallel in accordance with the output impedance and inductance of the current supply.
