  • Patent number: 11030780
    Abstract: Ultrasound B-mode images are reconstructed directly from transducer channel signals using a convolutional neural network (CNN). The CNN is trained with a dataset including, as inputs, simulated transducer array channel signals containing simulated speckle and, as outputs, corresponding simulated speckle-free B-mode ground truth images. After training, measured real-time RF signals taken directly from an ultrasound transducer array elements prior to summation are input to the CNN and processed by the CNN to generate as output an estimated real-time B-mode image with reduced speckle.

  • Patent number: 10912536
    Abstract: A method for ultrasound imaging detects a region of interest from ultrasound signals of a first imaging mode received along sensing elements of a transducer probe. The sensed data is analyzed and the system responds to the region of interest detection by switching to a secondary imaging mode with the transducer probe at the same position. The transducer probe indexes to a next scan position and sensing and analysis are repeated at each of a number of indexed scan positions.
