    摘要: A system includes at least one transducer configured to transmit at least one ultrasound pulse into a region of interest (ROI) of a patient. The pulse has at least a first frequency and propagates through a bodily structure in the ROI. The system further includes at least one receiver configured to receive at least one echo signal corresponding to the pulse. The echo signal includes the first frequency and at least one harmonic multiple of the first frequency. The system further includes a processor configured to automatically determine, from the at least one harmonic multiple, at least one boundary of the bodily structure. In an embodiment, the processor is configured to automatically determine, from the at least one harmonic multiple, an amount of fluid within the bodily structure.

    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.
