Abstract
A technique for fabricating a patterned conductor on the inner surface of a transparent tube comprises providing a source of conductive material inside a hollow tube and directing actinic radiation onto the tube wall where the deposition of a conductive pattern is desired to deposit conductive material thereon. That conductive deposit may be thickened by subsequent electroless or electroplating. The result is an improved magnetic resonance sensor comprising a hollow tube having "flat" conductor coils disposed on its interior surface.
