Title: The Innovations of William A. Johnsen
Introduction
William A. Johnsen is a notable inventor based in Parker, Colorado, who has made significant contributions to the field of medical imaging and annotation technologies. With a total of five patents to his name, Johnsen's work focuses on enhancing the accuracy and efficiency of anatomical structure analysis through innovative techniques.
Latest Patents
One of Johnsen's latest patents is titled "Multi-point annotation using a haptic plane." This invention involves an analysis technique where a three-dimensional (3D) image of a portion of an individual is iteratively transformed. The process facilitates the accurate determination of detailed multi-point annotation of anatomical structures. For a given marker point, the 3D image is translated and rotated based on information specifying a two-dimensional (2D) plane with an angular position in the 3D image. This allows the 2D plane to be presented in an orientation parallel to a reference 2D plane of a display. After receiving annotation information for the marker point, the 3D image is returned to its initial position and orientation. This method can be repeated for multiple marker points, showcasing the versatility and precision of Johnsen's invention.
