  • SYSTEMS AND METHODS FOR ELECTROMECHANICAL WAVE IMAGING WITH MACHINE LEARNING FOR AUTOMATED ACTIVATION MAP GENERATION
    Publication number: 20230363736
    Abstract: The present subject matter relates to techniques for electromechanical wave imaging. The disclosed system can include a processor that can be configured to perform an automated selection of at least one zero-crossing location using a heuristic-based baseline and/or a machine learning classifier and generate an electromechanical wave imaging isochrone based on the automated selection.

  • Systems and methods for rendering of cardiac electromechanical activation
    Patent number: 11678859
    Abstract: Systems and methods for generating an electromechanical map are disclosed herein. The methods includes obtaining ultrasound data comprising a series of consecutive image frames and radio frequency (RF) signals corresponding to the location in the heart; measuring displacements and strains based on the ultrasound data to determine an electromechanical activation in the location; converting the ultrasound data into a series of isochrone maps; and combining the series of isochrone maps to generate the electromechanical map. The electromechanical map illustrates the electromechanical activation and internal wall structures of the heart.

  • Triple mode ultrasound imaging for anatomical, functional, and hemodynamical imaging
    Patent number: 11419581
    Abstract: An ultrasonic imaging system acquires frames of echo data at a high acquisition frame rate using a single mode of acquisition. The echo data is used by three image processors to produce an anatomical image, a mechanical function image, and a hemodynamic image from the same echo data. A display displays an anatomical image, a mechanical function image, and a hemodynamic image simultaneously.
