    摘要： Aspects of the technology described herein relate to displaying indications of anatomical regions that have been imaged and/or that should be imaged next. In some embodiments, ultrasound data collected from a subject by an ultrasound device may be received, an automatic determination may be made that the ultrasound data was collected from a particular anatomical location, and an indication of the anatomical location may be displayed. In some embodiments, a plurality of anatomical locations may be determined for imaging, an anatomical location from among the plurality of anatomical locations may be automatically selected, and an indication of the anatomical location may be displayed. Displaying an indication of an anatomical location may include displaying or modifying a marker on a frame of a video of the subject such that the marker appears in the frame of the video to be located at the anatomical location on the subject.

    摘要： Aspects of the technology described herein related to controlling, using control circuitry, modulation circuitry to modulate and delay first ultrasound data generated by first ultrasound transducers positioned at a first azimuthal position of an ultrasound transducer array of an ultrasound device and second ultrasound data generated by second ultrasound transducers positioned at a second azimuthal position of the ultrasound transducer array of the ultrasound device, such that the first ultrasound data is delayed by a first delay amount and the second ultrasound data is delayed by a second delay amount that is different from the first delay amount. The first and second ultrasound data received from the modulation circuitry may be filtered and summed. The ultrasound transducer array, the control circuitry, the modulation circuitry, the filtering circuitry, and the summing circuitry may be integrated onto a semiconductor chip or one or more semiconductor chips packaged together.

    摘要： Aspects of the technology described herein relate to receiving an ultrasound image, automatically determining a location of a specific point on an anatomical structure depicted in the ultrasound image, and displaying an indicator of the location of the specific point on the anatomical structure on the ultrasound image. In some embodiments, the anatomical structure is a bladder. In some embodiments, the specific point is the centroid. In some embodiments, a statistical model determines the specific point. The indicator may be, for example, a symbol located at the specific point, a horizontal line extending through the specific point from one edge of the anatomical structure to another, and/or a vertical line extending through the specific point from one edge of the anatomical structure to another.

    摘要： Aspects of the technology described herein relate to apparatuses and methods for performing elevational beamforming of ultrasound data. Elevational beamforming may be implemented by different types of control circuitry. Certain control circuitry may be configured to control memory such that ultrasound data from different elevational channels is summed with stored ultrasound data in the memory that was collected at different times. Certain control circuitry may be configured to control a decimator to decimate ultrasound data from different elevational channels with different phases. Certain control circuitry may be configured to control direct digital synthesis circuitry to add a different phase offset to complex signals generated by the DDS circuitry for multiplying with ultrasound data from different elevational channels.
