摘要： A system and methods for automatically adjusting view angle when performing cardiac mapping and ablation are described herein. A three-dimensional (3D) map of a cardiac structure of a patient and a relative location (e.g., position and orientation) of a catheter within the cardiac structure may be displayed on a visual display device. According to an example procedure, the position and orientation of the tip of the catheter within the cardiac structure, and the current ablation target may be detected. A desired viewing angle of the ablation target may be known, determined, provided and/or learned through training sessions with the operator. The viewing angle of the 3D map of the cardiac structure may be automatically adjusted to correspond to the desired viewing angle using the known locations of the tip of the catheter and ablation target. Other details and procedures may be implemented, as described herein.

摘要： A method includes calculating a center-of-mass of a volume of an organ of a patient in a computerized anatomical map of the volume. A location is found on the anatomical map, on a surface of the volume, that is farthest from the center-of-mass. The location is identified as a known anatomical opening of the organ.

摘要： In one embodiment, a cardiac mapping system includes a medical examination device to capture data over time at multiple sample locations over a surface of at least one chamber of a heart, a display screen, and processing circuitry to process the captured data to determine a description of a propagation of activation wavefronts associated with activation times over the surface of the at least one chamber of the heart, calculate activation wavefront propagation path traces wherein each path trace describes a point on one activation wavefront being propagated over the surface of the at least one chamber of the heart according to an advancement of the activation wavefront such that the path traces describe the propagation of different points according to corresponding activation wavefronts, prepare a visualization showing the path traces on a representation of the at least one chamber, and render the visualization to the display screen.

摘要： Described embodiments include an apparatus that includes a display and processor. The processor is configured to receive, from a user, an input that indicates one or more points of interest on an electroanatomical map, of an anatomical surface, that is displayed on the display, and to superimpose on the map, in response to the input, a plurality of contours, each one of the contours being at a different respective geodesic distance, with respect to the surface, from the points of interest. Other embodiments are also described.

摘要： A method includes calculating a medial-axis tree graph of a volume of an organ of a patient in a computerized anatomical map of the volume. A predefined number of major branches in the tree graph are identified. Using the identified major branches, one or more known anatomical opening regions of the volume are identified in the anatomical map.
