Fluorolucent magnetic field generator

A fluorolucent magnetic transmitting array for generating a magnetic field for tracking of an object, the fluorolucent magnetic transmitting array comprising:

• a first fluorolucent magnetic transmitting element disposed in a first plane;
• and
• a second fluorolucent magnetic transmitting element disposed in a second plane, wherein the second fluorolucent magnetic transmitting element disposed in the second plane partially overlaps the first fluorolucent transmitting element disposed in the first plane,
• wherein each of the first fluorolucent magnetic transmitting element and the second fluorolucent magnetic transmitting element includes:
• a first spiral trace extending from a first outer origination point to a central origin in a first direction;
• and
• a second spiral trace extending from a second outer origination point to the central origin, wherein the first spiral trace is electrically coupled to the second spiral trace at the central origin,
• wherein the first spiral trace and the second spiral trace are creased at the central origin, and wherein an area of the first spiral trace overlaps with an area of the second spiral trace.

A magnetic transmitting assembly, comprising:

• a frame that includes a fluoro window;
• a first plurality of magnetic transmitting elements disposed on the frame on a first side of the fluoro window;
• a second plurality of magnetic transmitting elements disposed on the frame on a second side of the fluoro window, wherein the second side is disposed on an opposite side of the fluoro window from the first side,
• wherein the first plurality of fluorolucent magnetic transmitting elements and the second plurality of fluorolucent magnetic transmitting elements are disposed outside of the fluoro window.
