Abstract:
1. A system for determining a position of an imaging plane relative to a catheter, the system comprising: a first catheter having an ultrasound imaging transducer array, the ultrasound imaging transducer array corresponding to the imaging plane; a second catheter having a first antenna, the second catheter at least in part different than the first catheter; and a processor operable to determine angular position information of the imaging plane relative to one of the first catheter, the second catheter and combinations thereof as a function of a first signal of the first antenna; wherein the first catheter comprises a second antenna positioned relative to the ultrasound imaging transducer array, and wherein the processor is operable to determine the angular position information of the imaging plane as a function of a second signal of the second antenna; wherein the second antenna has a variable thickness as a function of angle around the first catheter.
