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.

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.

The systems and methods described herein generally relate to automatically determining an anatomical measurement of an ultrasound image. The systems and methods identify a view characteristic of an ultrasound image. The ultrasound image including one or more anatomical features. The systems and methods select a diagnostic measurement (DM) tool based on the view characteristic, on a graphical user interface (GUI), which is generated on a display. The systems and methods receive a first selection at a first position within the ultrasound image, and automatically determine an anatomical measurement, to be performed upon the ultrasound image utilizing the DM tool, based on the first position.

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.
