  • Template-less method for arbitrary radiopaque object tracking in dynamic imaging
    Patent number: 9471985
    Abstract: A method for localizing a fiducial marker in a medical image includes: obtaining the medical image; and performing an analysis, using an analysis unit, to localize the fiducial marker in the medical image; wherein the fiducial marker is localized by the analysis unit without use of a marker template.
    Type: Grant

  • Motion compensation for medical imaging and associated systems and methods
    Patent number: 9237860
    Abstract: Medical imaging and localization methods and systems for producing a motion-compensated image of a planning target volume (PTV) of a patient. In one embodiment, an imaging and localization system includes sensors that are positioned to receive an electromagnetic location signal from one or more active markers affixed to or adjacent a PTV. A signal processing component can produce real-time localization data corresponding to the location signal, and a system interface can receive such localization data. The system interface can also receive raw image data from an imaging subsystem and process the raw image data based on the localization data. For example, the imaging subsystem can include a computed tomography (CT) imaging system and image slices or frames can be binned based on the localization data.
