Ultrasound imaging system for generating a blended image including harmonic image data from a harmonic image and fundamental image data from a fundamental image based on determining a transition zone at which to blend the harmonic image and the fundamental image

A method comprising:

• controlling an ultrasound probe to acquire a fundamental image of a region of interest of a subject;
• controlling the ultrasound probe to acquire a harmonic image of the region of interest of the subject;
• generating a noise image based on noise image data acquired by the ultrasound probe;
• determining one or more values of the noise image that satisfy a threshold;
• determining a transition zone at which to blend the harmonic image and the fundamental image;
• generating a blended image including harmonic image data from the harmonic image and fundamental image data from the fundamental image based on determining the transition zone based on respective positions of the one or more values of the noise image that satisfy the threshold;
• and
• controlling a display to display the blended image.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of an ultrasound imaging system, cause the one or more processors to:

• control an ultrasound probe to acquire a fundamental image of a region of interest of a subject;
• control the ultrasound probe to acquire a harmonic image of the region of interest of the subject;
• generate a noise image based on noise image data acquired by the ultrasound probe;
• determine one or more values of the noise image that satisfy a threshold;
• determine a transition zone at which to blend the harmonic image and the fundamental image;
• generate a blended image including harmonic image data from the harmonic image and fundamental image data from the fundamental image based on determining the transition zone based on respective positions of the one or more values of the noise image that satisfy the threshold;
• and
• control a display to display the blended image.
