Abstract: Machine learning, artificial intelligence, and other computer-implemented methods are used to identify various semantically important chunks in documents, automatically label them with appropriate datatypes and semantic roles, and use this enhanced information to assist authors and to support downstream processes. Chunk locations, datatypes, and semantic roles can often be automatically determined from what is here called “context”, to wit, the combination of their formatting, structure, and content; those of adjacent or nearby content; overall patterns of occurrence in a document, and similarities of all these things across documents (mainly but not exclusively among documents in the same document set).

Abstract: Pulse field ablation (PFA) guidance is generated from intracardiac echocardiogram (ICE) imaging. The relative position of the PFA device and the tissue is determined. The treatment placement with respect to the tissue for repetitive application is detected. By finding the relative position and/or treatment placement over time, ICE imaging in combination with image processing may provide visual guidance rather than just imaging or just catheter tracking for PFA. The resulting PFA procedure may be more likely complete and/or optimized.
