Patent number: 10755378Abstract: During an analysis technique, a three-dimensional (3D) image of a portion of an individual is iteratively transformed to facilitate accurate determination of detailed multi-point annotation of an anatomical structure. In particular, for a given marker point, in response to receiving information specifying a two-dimensional (2D) plane having an angular position in the 3D image, the 3D image is translated and rotated from an initial position and orientation so that the 2D plane is presented in an orientation parallel to a reference 2D plane of a display. Then, after annotation information specifying the detailed annotation in the 2D plane of the given marker point is received, the 3D image is translated and rotated back to the initial position and orientation. These operations may be repeated for one or more other marker points.Type: GrantFiled: August 11, 2018Date of Patent: August 25, 2020Assignee: Echo Pixel, Inc.Inventors: Sergio Aguirre-Valencia, William Johnsen, Anthony Chen

Patent number: 10078885Abstract: During an analysis technique, a three-dimensional (3D) image of a portion of an individual is transformed to facilitate accurate determination of detailed annotation of an anatomical structure (such as: specifying the size of the anatomical structure based on annotation markers, an orientation of the anatomical structure, a direction of the anatomical structure and/or a location of the anatomical structure). In particular, in response to receiving information specifying a two-dimensional (2D) plane having an angular position in the 3D image, the 3D image is translated and rotated from an initial position and orientation so that the 2D plane is presented in an orientation parallel to a reference 2D plane of a display. Then, after information specifying the detailed annotation in the 2D plane is received, the 3D image is translated and rotated back to the initial position and orientation.Type: GrantFiled: June 30, 2016Date of Patent: September 18, 2018Inventors: Sergio Aguirre-Valencia, William Johnsen, Anthony Chen

Patent number: 5307292Abstract: A fractal-based or "patchwork" method for analyzing topographic data simulates covering the surface of a specimen surface with triangular patches in order to determine the relative surface area which is a function of patch size or scale of observation or interaction. The specimen surface has X and Y horizontal axes and a vertical Z axis. Height data is obtained for each point of a grid network of points on the surface, the points being arranged in parallel rows and the rows being spaced. The specimen surface is defined with triangles having a surface area equal to a preselected patch area value. The total area of the planar triangles is calculated to obtain a total measured area of value. The area of the specimen surface in the X-Y plane that is defined by the triangles is calculated to obtain a total measured area value. The total measured area value is divided by the total projected area value to obtain a relative area value.Type: GrantFiled: June 24, 1992Date of Patent: April 26, 1994Assignee: Christopher A.
