  • Patent number: 11810473
    Abstract: A system and method of training how to use a medical device using an instrument such as a mock ultrasound probe or syringe to be tracked in 3D space with six degrees of freedom using an internal optical camera, a light source (e.g. infrared LEDs), and a display of markers arranged on a surface. By extracting corner information for each marker, a 3D transformation can be established, allowing the system to know the instrument's position and orientation in 3D space relative to that marker. Each marker also encodes a numerical value corresponding to its predetermined position and orientation on the surface, allowing the instrument to determine its own position and orientation relative to the surface. Thus, as long as the instrument is able to see at least one marker on an optical surface, the system will know its full 3D position and orientation relative to the whole optical surface.

  • Patent number: 11769427
    Abstract: A training system to teach use of an ultrasound probe, the training system having a chamber defining an orifice, a shaft insertable into the orifice of the chamber, a marker positioned on the shaft at a distal end, a camera positioned to view the marker when inserted inside the chamber, and a processor operatively connected to the camera for processing a position and an orientation of the shaft based on the marker. The system provides a method for visualizing movement of the shaft from inside the chamber.

  • Patent number: 11120709
    Abstract: A system and method that improves the speed and efficiency through which ultrasound practitioners acquire and develop essential basic ultrasound skills in a simulated environment without the need of actual patients or subjects. The system utilizes a simulator with an input device that manipulates a virtual transducer probe in a simulated 3D space to cut a slice through a basic shape. A 2D section of the cut plane is also displayed so that the practitioner can learn to relate 2D section with their 3D objects cut in cross-section.
