  • Patent number: 11051886
    Abstract: A system and method for performing a navigation procedure including a surgical tool, an imaging device, and a computing device. The surgical tool is navigated to a target tissue located in a target area to perform a surgical procedure on the target tissue. The imaging device acquires image data of the target area while the surgical tool is being navigated to the target tissue by automatically traversing back and forth along a path relative to the target area and acquiring image data of the target area while traversing the path. The computing device receives the image data acquired by the imaging device and displays the image data such that the surgical tool can be navigated to the target tissue while simultaneously visualizing a position of the surgical tool relative to the target tissue from multiple perspectives relative to the target area.

  • Patent number: 10912536
    Abstract: A method for ultrasound imaging detects a region of interest from ultrasound signals of a first imaging mode received along sensing elements of a transducer probe. The sensed data is analyzed and the system responds to the region of interest detection by switching to a secondary imaging mode with the transducer probe at the same position. The transducer probe indexes to a next scan position and sensing and analysis are repeated at each of a number of indexed scan positions.

  • Patent number: 10806520
    Abstract: An imaging apparatus images a first object (10), like a tip of a catheter, disposed within a second object, such as a vascular structure of a person. A three-dimensional representation of the second object including a representation of a surface (23) of the second object and the position of the first object relative to the position of the second object are provided. A projection (22) of the first object onto the representation of the surface of the second object is determined and shown to a user like a physician on a display (18). The three-dimensional spatial relationship between the first object and the second object is thereby shown in a way that is very native for the user, i.e. a visualization can be provided, which allows the user to easily and accurately grasp the three-dimensional spatial relationship between the first object and the second object.

  • Patent number: 10765405
    Abstract: Reception beamforming that does not generate discontinuity in the vicinity of the depth of a transmit focus is executed even if reception scanning lines are disposed outside of the irradiation area of a focusing-type transmission beam. The degree of discontinuity showing the discontinuity of reception signals detected by plural ultrasound elements 105 or the degree of discontinuity regarding the discontinuity of the wave fronts of phased signals is detected by a discontinuity extracting unit 113. If there is an area where the degree of discontinuity is larger than a predefined value, a delay time generating unit 114 for discontinuity elimination changes the delay times in the area where the discontinuity is generated.
