摘要:
Methods and systems for placement of and/or placement planning for body surface electrodes are described. In some embodiments, body surface electrodes are used to generate intra-body electromagnetic fields sensed by intra-body probes for applications such as electrical field-guided catheter navigation and/or dielectric property-based tissue lesion assessment. Sizes and/or positions of body surface electrodes are optionally selected based on the results of electromagnetic simulations. Criteria for selection include, for example, potential gradient uniformity and/or intensity. In some embodiments, body surface electrode placement is performed under automated optical guidance. For example, images are obtained and used to indicate and/or assess body surface electrode placement. Optionally, indication is with respect to fiducial marks placed on the body, to which an electromagnetic simulation is spatially registered.
