  • Publication number: 20220409281
    Abstract: A computing device having a first processor configured to receive three-dimensional imaging data acquired by an imaging system, the three-dimensional imaging data being from ahead of a subject. The first processor can be configured to determine vascular structures from the three-dimensional imaging data, generate a three-dimensional model of the head of the subject from the three-dimensional imaging data, the three-dimensional model of the head including a three-dimensional model of the vascular structures and a three-dimensional model of a portion of a frontal horn of the subject, determine an entry point on the three-dimensional model of the head of the subject, determine a plurality of trajectories, each trajectory intersecting the three-dimensional model of the portion of the frontal horn and does not intersect the three-dimensional model of the vascular structures, and each trajectory is linear, and select a final trajectory from the plurality of trajectories.

  • Patent number: 11202652
    Abstract: Exemplary methods, apparatus, and systems are disclosed for automated registration and motion compensation of patient-mounted needle guide medical devices using fiducial markers, and processing algorithms where a re-registration step is provided. These methods, apparati, and systems adaptively compensate for the displacement of the medical device and/or target location due to the patient movement or internal organ motion.

  • Publication number: 20210153764
    Abstract: The present disclosure is directed to systems and methods for generating images using short tau inversion recovery, ultrashort echo time (STIR-UTE) MRI sequences. The STIR-UTE MRI sequences can be used to generate images that can differentiate between regions that are at temperatures that are either lethal or non-lethal to cell life. Thus, these sequences can be beneficial for implementations such as in monitoring cryoablation procedures.

  • Patent number: 10420626
    Abstract: Exemplary methods, apparatus, and systems are provided for automated detection and registration of medical images using fiducial markers and processing algorithms. By either clustering fiducial markers having a different number, size, shape, configuration, or material property or by using fiducial markers arranged in a ring shape, wherein their arrangement is asymmetric, and then applying a feature extraction to extract the fiducial marker objects, and registering the fiducial marker objects with a model of the fiducial frame, automatic registration can be achieved.

  • Patent number: 9993211
    Abstract: A system and method for automatic registration of medical images includes accessing image data of a subject and plurality of elongated fiducial markers arranged in an asymmetrical orientation and analyzing the image data to detect the elongated fiducial markers by applying a line filter to treat the elongated fiducial markers as lines within the image data. The system and method also includes matching the elongated fiducial markers within the image data to a model of the elongated fiducial markers, registering the image data with a coordinate system based on the matching, and generating a report indicating at least the registered image data.
