Abstract: A method includes accessing a computerized tomography (CT) scan of a human subject and defining a first two-dimensional (2D) slice (200) of the scan and a second 2D slice (204) of the scan, so that the first and the second slices intersect in an intersection line (224) defining a desired trajectory. The method further includes overlaying on the intersection line an icon (250) representing an object used in a procedure on the human subject, and rendering a three-dimensional (3D) image (650) of the human subject, incorporating the overlayed icon, from the CT scan.

Abstract: In one embodiment, a medical system includes a catheter to be inserted into a chamber of a heart, and including electrodes to capture electrical activity of tissue of the chamber over time, a display, and processing circuitry configured to compute a propagation of a cardiac activation wave over an anatomical map of the chamber from a start time in a cardiac cycle to an end time in the cardiac cycle responsively to the captured electrical activity, render to the display a sub-region of the anatomical map, select a time-bounded portion of the propagation of the cardiac activation wave commencing at a time after the start time responsively to when the propagation would commence to be rendered in the sub-region of the anatomical map, and render to the display the time-bound portion of the propagation of the cardiac activation wave on the sub-region of the anatomical map.

Abstract: A computer-implemented method includes obtaining a three-dimensional (3D) image of a region of a body of a patient, the 3D image having feature values. The 3D image is segmented to define one or more regions of interest (ROIs). At least one region of interest (ROI) feature threshold is determined. A background feature threshold is determined. A 3D model is generated from the 3D image based on the determined at least one ROI feature threshold, the determined background feature threshold, and the segmentation. The 3D model is output for display to a user.

Abstract: A method includes inserting a catheter into an organ of a patient and selecting, in a three-dimensional (3D) image of the organ, a plane of interest (POI). A first image, which includes an endoscopic view of the 3D image from a direction facing the POI, is produced. A second image, which includes a sectional view of the 3D image that is clipped by the POI, is produced, and the first and second images are displayed to a user.
