## Abstract

Various systems and methods are provided for generating a blended image including harmonic image data from a harmonic image and fundamental image data from a fundamental image. An ultrasound probe may be controlled to acquire a fundamental image of a region of interest of a subject and a harmonic image of the region of interest of the subject. A transition zone at which to blend the harmonic image and the fundamental image may be determined. A blended image including harmonic image data from the harmonic image and fundamental image data from the fundamental image may be generated based on determining the transition zone. A display may be controlled to display the blended image.
