Abstract: Methods for estimating of the effectiveness of catheter ablation procedures to form lesions. Lesion effectiveness parameters are received, and effectiveness of a corresponding ablation (optionally planned, current, and/or already performed) is estimated. The estimating is based on use by computer circuitry of an estimator constructed based on observed associations between previously analyzed lesion effectiveness parameters, and observed lesion effectiveness. The estimator is used by application to the received lesion effectiveness parameters.

Abstract: In some embodiments, data sensed and/or operational parameters used during a catheterization procedure are used in the motion frame-rate updating and visual rendering of a simulated organ geometry. The organ geometry is rendered as a virtual material using a software environment (preferably a graphical game engine) which applies simulated optical laws to material appearance parameters affecting the virtual material's visual appearance, as part of simulating a scene comprising the simulated organ geometry, and optionally also comprising simulated views of a catheter probe used for sensing and/or treatment. Optionally, measurements of and/or effects on tissue by sensing and/or commanded probe-tissue interactions are converted into material appearance changes, allowing dynamic visual simulation of intra-body states and/or events based on optionally non- visual input data. In some embodiments, physiology, motion physics, and/or other physical processes are simulated based on live inputs as part of associating material appearance properties to the simulated tissue's geometry.

Abstract: In some embodiments, a body cavity shape of a subject is reconstructed based on intrabody measurements of at least one property of an electromagnetic field by an intrabody probe (for example, a catheter probe) moving within a plurality of electrical fields intersecting the body cavity. In some embodiments, the electrical fields are generated at least in part from electrodes positioned in close proximity, for example, within 1 cm, of the body cavity. In some embodiments, the body cavity is a chamber of a heart (for example, a left atrium or left ventricle), and the electrodes used to generate the electrical field are positioned in the coronary sinus, a large vein occupying the groove between the left atrium and left ventricle. In some embodiments, known distances between measuring electrodes are used in guiding reconstruction, potentially overcoming difficulties of reconstruction from measurements of non-linear electrical fields.

Abstract: In some embodiments, data sensed and/or operational parameters used during a catheterization procedure are used in the motion frame-rate updating and visual rendering of a simulated organ geometry. In some embodiments, measurements of and/or effects on tissue by sensed and/or commanded probe-tissue interactions are converted into adjustments to the simulated organ geometry, allowing dynamic visual simulation of intra-body states and/or events based on optionally partial and/or non- visual input data. Adjustments to geometry are optionally to 3-D positions of simulated data and/or to simulated surface properties affecting geometrical appearances (e.g., normal mapping). Optionally, the organ geometry is rendered as a virtual material using a software environment (preferably a graphical game engine) which applies simulated optical laws to material appearance parameters affecting the virtual material's visual appearance. Optionally, physiology, motion physics, and/or other physical processes are simulated based on live inputs, as part of assigning geometrical adjustments to the simulated tissue.

Abstract: Disclosed herein is a method of graphically presenting an indicating marker over a 3-D model of a tissue surface during a catheterization procedure, comprising determining a region over the 3-D model, deforming the indicating marker to congruently match a shape defined by the 3-D model across the region at a plurality of positions; and rendering the 3-D model into an image including the deformed indicating marker by generating an image of the 3-D model covered by said deformed indicating marker.
