What is claimed is: 1. A method for simultaneously employing two or more different coil architectures in an electromagnetic (“EM”) tracking system, said method including: providing an EM transmitter, one or more EM receivers, and an EM receiver array, said EM transmitter comprising th
What is claimed is: 1. A method for simultaneously employing two or more different coil architectures in an electromagnetic (“EM”) tracking system, said method including: providing an EM transmitter, one or more EM receivers, and an EM receiver array, said EM transmitter comprising three single-coil transmitters and each of said EM receivers comprising three single-coil receivers, said receiver array comprising a plurality of single-coil receivers; tracking one or more of said single-coil transmitters of said EM transmitter with respect to said receiver array; and tracking one or more of said EM receivers with respect to said EM transmitter, wherein said step of tracking one or more of said single-coil transmitters of said EM transmitter with respect to said receiver array and said step of tracking one or more of said EM receivers with respect to said EM transmitter occur simultaneously. 2. The method of claim 1, wherein said EM transmitter is configured to be mounted on a patient anatomy. 3. The method of claim 1, wherein said EM receiver array is configured to be mounted on one or more of an x-ray detector and a surgical microscope. 4. The method of claim 1, wherein at least one of said EM receivers is configured to be mounted on a surgical instrument. 5. The method of claim 1, wherein one or more of said EM transmitter and said EM receivers is an Industry Standard Coil Architecture (“ISCA”) combination of three coils. 6. The method of claim 1, wherein said receiver array includes at least six single-coil receivers. 7. The method of claim 1, wherein said receiver array includes one or more dipole, nearly-dipole, and non-dipole coils. 8. The method of claim 1, wherein said step of tracking one or more of said single-coil transmitters of said EM transmitter with respect to said receiver array includes tracking each of said single-coil transmitters as an individual single-coil transmitter. 9. An electromagnetic (“EM”) tracking system configured to employ two or more different coil architectures simultaneously, said system including: an EM transmitter comprising three single-coil transmitters; one or more EM receivers each comprising three single-coil receivers; an EM receiver array comprising a plurality of single-coil receivers; and tracker electronics configured to track one or more of said single-coil transmitters of said EM transmitter with respect to said receiver array and to track one or more of said EM receivers with respect to said EM transmitter, wherein said tracker electronics is configured to simultaneously track one or more of said single-coil transmitters of said EM transmitter with respect to said receiver array and to track one or more of said EM receivers with respect to said EM transmitter. 10. The system of claim 9, wherein said EM transmitter is configured to be mounted on a patient anatomy. 11. The system of claim 9, wherein said EM receiver array is configured to be mounted on one or more of an x-ray detector and a surgical microscope. 12. The system of claim 9, wherein at least one of said EM receivers is configured to be mounted on a surgical instrument. 13. The system of claim 9, wherein one or more of said EM transmitter and said EM receivers is an Industry Standard Coil Architecture (“ISCA”) combination of three coils. 14. The system of claim 9, wherein said receiver array includes at least six single-coil receivers. 15. The system of claim 9, wherein said receiver array includes one or more dipole, nearly-dipole, and non-dipole coils. 16. The system of claim 9, wherein said tracker electronics is configured to track each said single-coil transmitters as an individual single-coil transmitter. 17. A computer-readable storage medium including a set of instructions for a computer, said instructions including: an individual coil tracking routine configured to track one or more of an orientation and a position of each single-coil transmitter in an Industry Standard Coil Architecture (“ISCA”) transmitter with respect to an array of single-coil receivers; a group coil tracking routine configured to track one or more of an orientation and a position of said ISCA transmitter with respect to an ISCA receiver, wherein said individual coil tracking routine and said group coil tracking routine are configured to track one or more of said single-coil transmitter orientation and said single-coil transmitter position simultaneously with one or more of said ISCA transmitter orientation and said ISCA transmitter position. 18. The set of instructions of claim 17, wherein said array includes at least six single-coil receivers. 19. The set of instructions of claim 17, wherein said array includes one or more dipole, nearly-dipole, and non-dipole receiver coils.
