摘要： An ultrasound beamforming probe includes an array of transducer elements and a processing board that carries a signal processor. Receive signal connections, for a receive aperture formed from multiple transducer elements, are coupled to the first signal processor. A location memory is connected to the signal processor and holds a spatial location for the receive aperture. The signal processor retrieves the spatial location, determines a beamforming phase shift derived from the spatial location for each transducer element in the receive aperture, and applies the respective phase shift to each receive signal.

摘要： A method and apparatus for acquiring multi-line acquisition ultrasound data. Ultrasound signals are transmitted into an area of interest. Echo signals are acquired and analyzed to produce a first data stream associated with a first receive beam. The first data stream is decimated by removing at least two consecutive data samples therefrom, while passing at least two consecutive data samples to form a first decimated data stream. Using this decimation pattern, a bandwidth of one-half to three-quarters of the data sampling rate after decimation may be achieved.

摘要： An ultrasound machine is disclosed that displays a color representation of moving structure, such as a cardiac wall tissue, within a region of interest on a monitor. The color representation is generated by displaying color hues corresponding to a movement parameter of the structure, such as velocity or strain rate in such a manner as to provide for quantitative visualization of movement parameter gradients. The movement parameter is mapped to the color hues by apparatus comprising a user interface that allows the user to input color band resolution and a local range of relative parameter values. A front-end generates received signals in response to ultrasound waves. A Doppler processor generates a set of parameter signals representing absolute values of the movement parameter within the structure. A set of color characteristic signals is generated by a display processor in response to the set of parameter signals and to a user-defined local range of relative parameter values. The color characteristic signals, representative of the gradient of the movement parameter of the moving structure, are displayed as a color representation on a monitor.

摘要： An ultrasound machine that generates a color representation of moving structure, such as 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 set of signal values of the structure, such as velocity or strain rate. The related feature of the set of signal values 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 signal values representing a spatial set of values of the moving structure. A host processor embodies a tracking function and a time integration function to generate tracked movement parameter profiles and displacement parameter values over a time period corresponding to sampled anatomical locations within the region of interest. The displacement parameter values are then mapped to color characteristic signals. A display processor maps the values of the color characteristic signals to the displacement parameter values, representing the moving structure, to display a color representation, on a monitor.

摘要： Methods and apparatuses for processing ultrasound signals. An approximation signal is generated to approximate an undesirable component of an input signal. The input signal may represent an ultrasound (e.g., Doppler) echo from a body. The approximation signal is used to remove the undesirable component from the input signal, leaving an output signal, which may be further processed by an ultrasound measurement and/or imaging system.
