Synthesis of magnetic gradients for NMR tomography

Magn Reson Imaging. 1990;8(2):101-5. doi: 10.1016/0730-725x(90)90242-t.

Abstract

A numerical method is applied to calculate an optimal distribution of currents in air which generate the magnetic field gradients required to spatially encode the radiofrequency signal in a NMR tomographic experiment. We compare the performances of the gradient circuits for the whole body air-core electromagnet described by Bangert and Mansfield (J. Phys. E 15; 1982) with the results of our optimization.
