  • Patent number: 10546396
    Abstract: A system for registering a group of images of an anatomical region of a patient in a coordinate system of a medical system is disclosed. The system includes an object disposed in a known position in the coordinate system. In one embodiment, the object has a first state in which the object is visible in at least one image and a second state in which the object is invisible in at least another image. In another embodiment, the object is substantially invisible to the eye in each image, but detectable by image processing. The system includes an electronic control unit configured to process the images to identify an image location of the object, create a transformation model responsive to the image location and the known position of the object in the coordinate system, and register the group of images in the coordinate system using the model.

  • Patent number: 10271810
    Abstract: An apparatus includes a positioning system and a patient reference sensor (PRS). The positioning system acquires a plurality of raw PRS readings over time, which can indicate the position and orientation of the PRS. A filter is configured to process the raw PRS readings and output filtered PRS readings. The filter outputs filtered PRS readings as a baseline value while the raw PRS readings stay within a predetermined range and output filtered PRS readings as unchanged raw PRS readings when the raw PRS readings reach or vary outside of the predetermined range. A motion compensation function generated based on at least the filtered PRS readings can be used to correct a subject position and orientation (P&O) to compensate for the motion of the moving region of interest over time.

  • Publication number: 20180098716
    Abstract: A system for superimposing virtual anatomical landmarks on an image includes a medical positioning system (MPS) for producing location readings with respect to points within a region of interest in accordance with an output of a location sensor disposed in a medical device. A coordinate system of the MPS is registered with an image coordinate system. A control unit receives a signal from a user to record a location reading when the medical device is at a desired point in the region of interest where the user desires to place a virtual landmark, modifies the recorded location reading for motion compensation, transforms the motion-compensated location reading from the MPS coordinate system to the image coordinate system to produce a target location, and then superimposes a representation of the virtual landmark on the image at the target location.
