Abstract

A wire form includes a conductor having a distal end and a proximal end. The conductor is coiled and has a predetermined spacing between adjacent coils. The predetermined spacing provides a parasitic capacitance and an inductance. The parasitic capacitance and inductance have a resonance frequency tuned to about an excitation signal's frequency of a magnetic-resonance imaging scanner.
