ULTRASOUND-BASED GEOMETRY DETERMINATION FOR ELECTROPHYSIOLOGICAL MAPPING

Systems and methods can be used for ultrasound-based geometry determination for cardiac mapping. A patient can be scanned with an ultrasound while wearing body surface electrodes. While the scanning takes place, the location of the ultrasound transducer can be tracked in three-dimensional space. The electrodes can be tracked and located in the same coordinate system as the image volume. Therefore, each electrode's location can be determined relative to the acquired image volume such that corresponding geometry data is generated for the heart and the electrodes.
