    Abstract: A method and ultrasound imaging system for detecting a coherent reflector includes acquiring ultrasound channel data from a volume with a probe, calculating a transform function from the ultrasound channel data, identifying a first angle of a projection of the coherent reflector in a plane parallel to the 2D aperture based on the transform function, detecting a line-shaped echo pattern in the ultrasound channel data, and determining a second angle of the coherent reflector with respect to the 2D aperture based on the position of the line-shaped echo pattern. The method and system includes determining a position and orientation of the coherent reflector based on the first angle and the second angle, enhancing a representation of the coherent reflector in an image generated based on the ultrasound channel data, and displaying the image on a display device after enhancing the representation of the coherent reflector.

    Abstract: Example apparatus, systems, and methods for image data processing are disclosed and described. An example system includes an image capturer to facilitate capture of an image. The example system includes a Doppler spectrum recorder to record a Doppler spectrum. The example system includes a study type inferrer to infer a study type associated with the Doppler spectrum by: processing the Doppler spectrum using at least one neural network to generate a first probability distribution among study type classifications; processing the image using the at least one neural network to generate a second probability distribution among the study type classifications; and combining the first probability distribution and the second probability distribution to infer a study type.

    Abstract: Methods and systems for segmenting structures in medical images are provided. The methods and systems drive a plurality of transducer element, and collect receive signals from the transducer array at a receive beamformer to form beam summed signals. The methods and systems generate a first ultrasound image of a region of interest (ROI) having tissue elements and blood elements, and generate a second ultrasound image of the ROI having tissue elements and blood elements. The tissue elements of the first ultrasound image having a higher intensity than the blood elements. The blood elements of the second ultrasound image having a higher intensity than the tissue elements. The methods and systems further perform segmentation by simultaneously applying edge detection on the first and second ultrasound images for the ROI.
