SYSTEM FOR EXCITATION LEADLESS MINIATURE MARKER

摘要

A system for generating a excitation field for excitation of a leadless marker assembly. One aspect of the system comprises a source generator assembly having a power supply, an energy storage device, a switching network and a source coil interconnected and configured to deliver a magnetic excitation signal waveform. The power supply is configured to deliver power to energize the energy storage device. The switching network is configured to: direct electrical current through the source coil alternately switch between a first on position and a second on position alternately transfer stored energy from the energy storage device to the source coil and to transfer stored energy from the source coil back to the energy storage device and the source coil being coupled to the switching network to generate a excitation signal.
