摘要： Embodiments are described for a system and method to improve image clarity 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 region-of-interest may include an organ, an organ cavity, for example a bladder, or a portion of an organ or organ cavity. The echoic signals then receive signal processing via an executable algorithm 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. The algorithm generates a harmonic value that may then be plotted on a grid or render a map presentable on a computer display or other visual means. Alternate embodiments provide that the executable algorithm may be non-parametric and 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-coding according to the magnitude of the harmonic value, to present an image of the region-of-interest.

摘要： A hand-held 3D ultrasound instrument is disclosed which is used to non-invasively and automatically measure amniotic fluid volume in the uterus requiring a minimum of operator intervention. Using a 2D image-processing algorithm, the instrument gives automatic feedback to the user about where to acquire the 3D image set. The user acquires one or more 3D data sets covering all of the amniotic fluid in the uterus and this data is then processed using an optimized 3D algorithm to output the total amniotic fluid volume corrected for any fetal head brain volume contributions.
