Abstract
Systems, methods, and computer-readable media for optimizing an electromagnetic navigation system are provided. Multiple test signals corresponding to multiple combinations of phase offset values of a plurality of frequency components, respectively, are generated. Based on the test signals, a table including peak signal amplitudes associated with the respective test signals is generated. A minimum value of the stored peak signal amplitudes is identified in the table. Based on the table, a determination is made as to which combination of phase offset values is associated with the minimum value of the stored peak signal amplitudes. The determined combination of phase offset values is stored in a memory for use, during an electromagnetic navigation procedure, in generating a signal including the frequency components having the determined combination of phase offset values, respectively.
