    Abstract: A controller (240/340) for simultaneously tracking multiple interventional medical devices includes a memory (242/342) that stores instructions and a processor (241/341) that executes the instructions. When executed by the processor (241/341), the instructions cause the controller to execute a process that includes receiving timing information from a first signal emitted from an ultrasound probe (252/352) and reflective of timing when the ultrasound probe (252/352) transmits ultrasound beams to generate ultrasound imagery. The process executed by the controller also includes forwarding the timing information to be available for use by a first acquisition electronic component (232/332). The first acquisition electronic component (232/332) also receives sensor information from a first passive ultrasound sensor (S1) on a first interventional medical device (212/312). The timing information is used to synchronize the sensor information from the first passive ultrasound sensor (S1) on the first interventional medical device (212/312) with sensor information from a second passive ultrasound sensor (S2) on a second interventional medical device (216/316).

    Abstract: Ultrasound imaging systems and methods for generated clutter-reduced images are provided. For example, an ultrasound imaging system can include an array of acoustic elements in communication with a processor. The processor is configured to activate the array to perform a scan sequence to obtain a plurality of signals, identify off-axis signals from the plurality of signals by comparing the right subaperture and the left subaperture, and create a clutter-reduced image based on the comparison. Because off-axis signals are more likely to create image clutter, reducing the influence of off-axis signals on the image can therefore improve the quality of the image. Accordingly, embodiments of the present disclosure provide systems, methods, and devices for generating ultrasound images that have reduced or minimized clutter, even for images obtained using arrays that do not satisfy the Nyquist criterion.

    Abstract: A tool navigation system employing an ultrasound probe, an ultrasound scanner, an interventional tool, a tool tracker and an image navigator. In operation, the ultrasound probe generates an acoustic image plane for scanning an anatomical region, and the ultrasound scanner generates an ultrasound image of the anatomical region from a scan of the anatomical region. During the scan, the interventional tool is navigated within the anatomical region relative to the acoustic image plane, and the tool tracker tracks a position of the interventional tool relative to the acoustic image plane. The image navigator displays a graphical icon within the ultrasound image for illustrating a tracking of the interventional tool relative to the acoustic image plane by the tool tracker. Additionally, a special attachment on the US probe with PZT type sensors can help this navigation by emitting acoustic waves off the central axis of the imaging plane.
