Publication number: 20230039065Abstract: A three-dimensional geometric image of an anatomical region is generated from a plurality of two-dimensional echographic image slices of the region. The image slices are filtered using a reaction-diffusion partial differential equation model before being arranged into a voxel space. Each voxel is then assigned a voxel value to create a volumetric data set from which the volumetric image can be rendered. The image is rendered from far to near, relative to a preset viewing direction, by an alpha-blending process. The alpha value at any given voxel can be determined using the magnitude of the density gradient vector at that voxel. Similarly, the direction of the density gradient vector at a given voxel can be used as a surface normal vector for shading purposes at that voxel.Type: ApplicationFiled: January 14, 2021Publication date: February 9, 2023Inventors: Lorina DASCAL, Oded SUDARSKY, Jacob SEGEV, Alexander DATHSKOVSKY, Yaron VALACH, Maxim YORESH

Publication number: 20200138334Abstract: Provided herein are systems and methods for use in identifying location of electrodes of a catheter within a three-dimensional space. The systems and methods initially predict locations of physical electrodes and/or physical magnetic sensors of the catheter in the three-dimensional space. Impedance and/or magnetic responses are predicted for the predicted locations. Actual measurements/responses (e.g., measured responses) are then obtained for the physical electrodes and/or physical sensors. Based on the predicted responses and the measured responses, the systems and methods generate calculated locations of electrodes and/or sensors in the three-dimensional space. The systems and method utilize information from both the predicted responses and the measured responses to produce the calculated locations, which may have an accuracy that is greater than locations produced by either the predicted responses or the measured responses.Type: ApplicationFiled: October 29, 2019Publication date: May 7, 2020Inventors: ANTHONY D. HILL, YURIY MALININ, CABLE THOMPSON, SILVINIA RYBNIKOV, MAXIM YORESH, ODED SUDARSKY

Patent number: 6088035Abstract: In a process for rendering a 3-dimensional graphics scene made up of a plurality of static and/or dynamic objects composed of geometrical elements, a method for obviating redundant processing and communications involved with hidden dynamic objects, so as to accelerate the rendering of successive images of the scene and to reduce communications requirements (FIG. 6C). The method includes in respect of each occluded dynamic object: (a) predicting a time period during which the object is expected to remain occluded; (b) generating a volume that contains the object during the time period; (c) inserting the volume into a spatial data structure used by an occlusion culling technique; (d) applying the occlusion culling technique so as to output-sensitively render the scene, yet not rendering or updating the occluded dynamic object during the time period, provided the occlusion culling technique does not find the volume to be visible.Type: GrantFiled: February 23, 1998Date of Patent: July 11, 2000Assignee: Virtue, Ltd.Inventors: Oded Sudarsky, Graig J.
