  • Publication number: 20240261032
    Abstract: Aspects of the disclosure may involve a method of generating resection plane data for use in planning an arthroplasty procedure on a patient bone. The method may include: obtaining patient data associated with at least a portion of the patient bone, the patient data captured using a medical imaging machine; generating a three-dimensional patient bone model from the patient data, the patient bone model including a polygonal surface mesh; identifying a location of a posterior point on the polygonal surface mesh; creating a three-dimensional shape centered at or near the location; identifying a most posterior vertex of all vertices of the polygonal surface mesh that may be enclosed by the three-dimensional shape; using the most posterior vertex as a factor for determining a posterior resection depth; and generating resection data using the posterior resection depth, the resection data configured to be utilized by a navigation system during the arthroplasty procedure.

  • Publication number: 20230329813
    Abstract: Systems, methods, and guidance techniques for guiding placement of a robotic manipulator relative to an anatomy. A localizer tracks the robotic manipulator and the anatomy. Controller(s) obtain workspace parameters of the robotic manipulator and capture, from the localizer, a current state of the robotic manipulator relative to the anatomy. The controller(s) capture, from the localizer, states of the anatomy in response to movement of the anatomy according to a prescribed manner or a predetermined manner and determine operative parameters of the anatomy based on the captured states. The controller(s) compare the workspace parameters to the operative parameters to determine a desired state for the robotic manipulator relative to the anatomy, whereby the workspace parameters of the robotic manipulator have an acceptable relationship with respect to the operative parameters of the anatomy. The controller(s) guide placement of the robotic manipulator from the current state to the desired state.

  • Publication number: 20220328285
    Abstract: Methods and apparatus for processing a substrate are provided herein. For example, a gas supply configured for use with a processing chamber includes an ampoule that stores a precursor and comprises an input to receive a carrier gas and an output to provide a mixture of the carrier gas and the precursor to the processing chamber and a sensor assembly comprising a detector and an infrared source operably connected to an outside of an enclosure, through which the mixture flows, and a gas measurement volume disposed within the enclosure and along an inner wall thereof so that a concentration of the precursor in the mixture can be measured by the detector and transmitted to a controller.
