  • Publication number: 20190269384
    Abstract: An ultrasound imaging system includes a processor to associate an ultrasound image with one or more pictographs that correspond to the image. A processor provides ultrasound image data to one or more trained neural networks that classify the image data. The processor is programmed to select one or more pictographs that correspond to the classified image data for presentation to the operator. In some embodiments, the processor is programmed to use a neural network to determine if an ultrasound image captured during an examination corresponds to one or more required views for a particular type of examination.

  • Patent number: 10226236
    Abstract: Adjustment of operation of an ultrasound imaging system may be based at least in part on one or more characteristics represented in ultrasound return signals from two or more sample volumes. Adjustment may include adjusting a principal sample volume location or selecting a new principal sample volume. For example, a location of a principal sample volume may be adjusted or new principal sample volume selected so as to remain focused on an identified region of interest or to maintain the principal sample volume relative to some structure or reference. The principal sample volume may be maintained in the center or along a centerline of an artery or other structure, as the transducer array is moved along the artery or structure.

  • Patent number: 9848851
    Abstract: An ultrasound imaging system and method employs hardware and/or software to monitor values indicative of analog-to-digital converter (ADC) saturation for each channel as a function of depth. Any of a number of actions may be performed based on the monitored values. For example, analog amplification or TGC may be adjusted to enhance the use of a dynamic range of ADCs while reducing or eliminating ADC saturation. A TGC profile may be adjusted. An alert may be provided. A power consumption may be adjusted.

  • Patent number: 9151832
    Abstract: Disclosed are systems and methods which efficiently control storage of and/or access to data which includes repetitive data or data which is used by different modes, processes, etcetera. Embodiments provide control for storage of and/or access to large amounts of data used in ultrasound system beam forming for image generation using a hierarchy of sequencers for controlling storage of and/or access to data. A frame sequencer may provide control at a frame level while an address sequencer is implemented to provide control at a data access level.

  • Patent number: 6622003
    Abstract: A method for developing an electronic course may include describing an illustrative scenario that presents a problem for a student of an electronically deliverable course. At least one possible role assignment for a corresponding student of the course may be defined based on the illustrative scenario. A task may be provided for the student based on the role assignment and the scenario. A guidance system may be established which is accessible to the students over the electronic communications network. The guidance system provides guidance for solving the task or problem associated with the scenario.
