1. A medical imaging system, comprising:
a magnetic field generating assembly, including:
a first conductive coil located on a first plane, the first conductive coil including a first elongate conductive element wound around a first central axis in a first spiral formation, the first elongate conductive element having a first width,
a second conductive coil located on a second plane, the second conductive coil including a second elongate conductive element wound around a second central axis in a second spiral formation, the second elongate conductive element having a second width, wherein the first spiral formation and the second spiral formation each have a rectangular shape including a plurality of rectangular coils bends,
a dielectric substrate layer located between the first conductive coil and the second conductive coil, and
an isolated pattern of conductive elements located within the dielectric substrate layer between the first conductive coil and the second conductive coil.
