Abstract
Although magnet coil windings are distributed discontinuously, the distribution of magnetic fields generated actually approaches a desired continuous distribution. The desired continuous distribution is defined analytically, as closely as possible. A system for acquiring magnetic resonance data has a coil segment formed by winding a conductor on a bobbin representing an axial direction. A magnetic field is generated by supplying current into the conductor. Winding positions at which the conductor is wound turn-by-turn on the bobbin are determined in agreement with a specified current step value and sequentially from a winding positioned at an outermost end of the coil segment in the axial direction. Additionally, a shunt element for shunting the current carried turn-by-turn is arranged in the coil segment in relation to a pattern of turns of the coil segment by winding the conductor into a plurality of current flows through a plurality of shunt paths.
