<p>A system and method to improve image cla.pi.ty in ultrasound images that utilize an ultrasound transceiver receiving ultrasound energy returning from a targeted region of interest and producing a plurality of echoic signals The echoic signals then receive signal processing via an executable algo.pi.thm configured to image the targeted region-of-interest from the echoic signals using at least one of a first harmonic, a second harmonic, and a fundamental frequency of the ultrasound energy Alternate embodiments provide that the executable algonthm may include a Harmonic Analysis Kernel (HAK) The HAK includes a window process, a Fast Fourier Transform process, an average process, a normalization of intensity process, a compensation by depth process, and a harmonic smoothing process to generate the harmonic values A map of the harmonic values then may be coded, for example, by color according to the magnitude of the harmonic value, to present an image of the region-of-interest</p> |
