A magnetic resonance RF coil comprises a conductive material deposited on
a dielectric substrate. The conductive material includes magnetic field
generating elements used to generate an RF magnetic field and
interdigital capacitor elements. The capacitor elements are oriented
parallel to the magnetic field generating elements and, therefore, to a
main static magnetic field within which the coil is to be located. This
orientation minimizes arcing resulted from emitted electrons and helps to
prevent catastrophic breakdown of the coil.
