摘要： A method and an apparatus for imaging blood motion by displaying an enhanced image of the fluctuating speckle pattern. The first step in the blood motion image processing is high-pass filtering of the signal vector from each range gate. Following high-pass filtering, a speckle signal is formed. The speckle signal is then subjected to a nonlinear scale conversion. The resulting speckle signal is displayed as the desired blood motion image concurrently with a corresponding tissue image.

摘要： A method and an apparatus for imaging blood motion by displaying an enhanced image of the fluctuating speckle pattern. A continuous stream of data frames, each the result of one scan, is available for processing. For each position in the scan plane, a respective time sequence of signal samples is available for processing. The first step in the blood motion image processing is high-pass filtering of this signal. Following the high-pass filter, a speckle signal is formed, e.g., by calculating the squared magnitude (i.e., power) of the high-pass-filtered signal (I/Q or RF). The resulting speckle signal can then undergo a nonlinear amplitude transformation to form a blood motion imaging signal for display.

摘要： An ultrasound machine is disclosed that generates a color representation of moving structure, such as a cardiac wall tissue within a region of interest, and is displayed on a monitor. The color representation is generated by displaying at least one color characteristic related to a movement parameter of the structure, such as mean velocity or mean strain rate. The related feature of the movement parameter is mapped to the color characteristic by an apparatus comprising a front-end that generates received signals in response to backscattered ultrasound waves. A Doppler processor generates a set of parameter signals representing a spatial set of values of the movement parameter within the structure. A host processor embodies a tracking function and a peak-detection function to generate a set of tracked movement parameter profiles and a set of peak values of the movement parameter over a time period corresponding to anatomical locations within the region of interest. The set of peak values of the movement parameter are then mapped to a set of color characteristic signals. A display processor applies the mapped values of the color characteristic signals to the set of peak values of the movement parameter, representing the moving structure, to display a color representation, on a monitor.

摘要： An ultrasound system and method for calculation and display of tissue deformation parameters are disclosed. An ultrasound acquisition technique that allows a high frame rate in tissue velocity imaging or stain rate imaging is employed. The tissue deformation parameter strain is determined by an accumulation of stain rate estimates for consecutive frames over an interval. The interval may be a triggered interval generated by, for example, an R-wave in an ECG trace. The strain calculation may be improved by moving the sample volume from which the stain rate is accumulated from frame-to-frame according to the relative displacement of the tissue within the original sample volume. The relative displacement of the tissue is defined by the instantaneous tissue velocity of the sample volume. An estimation of strain rate based upon a spatial derivative of tissue velocity is improved by adaptively varying the spatial offset, dr. The spatial offset, dr, can be maximized to cover the entire tissue segment (e.g., heart wall width) while still keeping both of the sample volumes at each end of the offset within the tissue segment. This nay be accomplished by determining whether various parameters (e.g., grayscale value, absolute power estimate, magnitude of the autocorrelation function with unity temporal lag and/or magnitude of strain correlation) of the sample volumes within in the spatial offset are above a given threshold.

摘要： An ultrasound machine that generates a pattern of indicia corresponding to tracked moving structure, such as a cardiac wall tissue that is displayed on a monitor. The pattern of indicia is generated by displaying a set of tagging symbols related to the tracked movement of the structure over a time period by an apparatus comprising a front-end that generates received signals in response to backscattered ultrasound waves. A Doppler processor generates a spatial set of signals values representing movement within the structure. A non-Doppler processor generates a set of parameter signals representing a spatial set of B-mode values within the structure. A host processor embodies a tracking function to generate a set of tracked movement parameter profiles and motion parameter profiles over a time period corresponding to anatomical locations associated with the set of tagging symbols. A display processor overlays the set of tagging symbols onto an image of the moving structure on a monitor, such as B-mode, showing a pattern of indicia that allows visualization of the expansion and contraction of the moving structure in real-time over the time period.
