Imaging to determine electrode geometry

A system comprising:

• an optical imaging device configured to generate imaging data containing one or more image frames of a body surface of a patient including a plurality of electrodes that have been positioned on the body surface and in direct line of sight during image capture by the optical imaging device;
• non-transitory memory to store machine readable instructions and data, the data comprising geometry information for an anatomical envelope and the body surface;
• at least one processor to access the memory and execute the instructions to perform a method that comprises:
• determining three-dimensional electrode locations and surface geometry from the imaging data, the determined three-dimensional electrode locations and surface geometry including estimated locations for hidden electrodes outside of the direct line of sight during image capture by the optical imaging device;
• registering the determined three-dimensional electrode locations and surface geometry with the geometry information for the anatomical envelope and the body surface to provide aggregate geometry data describing a three-dimensional spatial relationship between the plurality of electrodes and the anatomical envelope;
• and
• storing the aggregate geometry data in the memory.

One or more non-transitory computer-readable media having instructions programmed to perform a method comprising:

• storing imaging data containing one or more image frames of a body surface of a patient including a plurality of electrodes positioned on the body surface and in direct line of sight during image capture by an optical imaging device;
• determining three-dimensional electrode locations and surface geometry based on the imaging data, in which the determined three-dimensional electrode locations and surface geometry includes estimated locations for hidden electrodes outside of the direct line of sight during image capture by the optical imaging device;
• registering the determined three-dimensional electrode locations and surface geometry with predetermined anatomical geometry information, which describes a spatial relationship between the body surface and an anatomical envelope, to provide aggregate geometry data describing a three-dimensional spatial relationship between the plurality of electrodes and the anatomical envelope;
• and
• storing the aggregate geometry data in the memory.
