Methods and systems for projection profile enabled computer aided detection (CAD)

A system, comprising:

• an ultrasound device, comprising at least one processor, wherein the ultrasound device is configured to:
• generate volumetric ultrasound dataset, based on echo ultrasound signals;
• generate based on the volumetric ultrasound dataset, a three-dimensional (3D) ultrasound volume;
• and
• apply selective structure detection to the three-dimensional (3D) ultrasound volume, the selective structure detection comprising:
• generating based on a projection of the three-dimensional (3D) ultrasound volume in a particular spatial direction, a two-dimensional (2D) image;
• applying two-dimensional (2D) structure detection to the two-dimensional (2D) image, wherein the two-dimensional (2D) structure detection is configured to identify structure candidates associated with a particular type of structures, the particular type of structures comprising abnormal tissue structures in a particular body part;
• selecting for each identified structure candidate, a corresponding local volume within the three-dimensional (3D) ultrasound volume;
• applying three-dimensional (3D) structure detection to each selected local volume, wherein:
• the three-dimensional (3D) structure detection is configured to compare characteristics associated with the structure candidate with the particular type of structures, and
• the three-dimensional (3D) structure detection is applied at full-resolution to each selected local volume;
• and
• identifying based on applying the three-dimensional (3D) structure detection, one or more structure candidates that match the particular type of structures.
