Abstract
A method for producing planar gradient coils for MRI systems includes defining a planar surface along which one continuous current wire extends along a path for generating a gradient field along a spatial direction; defining the path of the continuous current wire as a spiral path of a single continuous wire filament; describing the spiral path of the continuous current wire by a parametric curve according to a modified version of the Pascal Limaçons curve combined with the Archimede's spiral; applying the Biot-Savart law to evaluate the magnetic field generated by the continuous current wire extending along the spiral path; optimizing the parameters of the parametric curve for shaping the spiral path of the continuous current wire to generate a linear magnetic gradient field along the spatial direction and which gradient magnetic field is linear inside a predetermined volume of space permeated by the linear magnetic gradient field.
