Model of an NMR imaging "bird cage" coil: Enhancing axial homogeneity of the magnetic field

A bird cage coil was modified in order to increase the longitudinal magnetic field. This was obtained using a phase difference circuit between the internal wires. model based on the circuit theory. Theoretical results show the advantage of this modified structure.
