摘要： Embodiments of the present invention may provide an ultrasound imaging system and method for forming multiple receiving scan lines from one original receiving scan line. Ultrasound signals reflected from one original receiving scan line are converted into analog signals having a center frequency. The analog signals are converted into digital data. The digital data are coarsely delayed, wherein the coarsely delayed data are extracted at a rate of n-times of the center frequency. Data of the multiple receiving scan lines are formed by performing fine delay and interpolation. For the interpolation, parts of the extracted data are selected at a rate of n-times of the center frequency and the multiple receiving scan lines.

摘要： An ultrasound diagnostic system and a method for forming IQ data without a quadrature demodulator are disclosed. Ultrasound echoes from a target object are converted into analog signals, which have a center frequency. The analog signals are converted into digital signals and parts of the digital signals are extracted at a rate of n-times of the center frequency, wherein “n” is a positive integer. Focused-receiving signals are formed with the extracted digital signals and IQ data are obtained by selecting at least one pair of the focused-receiving signals. The focused-receiving signals in each pair have a phase difference of λ/4 with respect to each other, where “λ” is a wavelength determined with the center frequency.

摘要： An ultrasonic diagnostic imaging system is provided for scanning with a linear transducer array and displaying an image area which is truncated with respect to a conventional triangular image sector to take the form of a trapezoid. Uniformity of image resolution and ease of signal processing enhancement is provided by transmitting adjacent ultrasonic beams at equal angular increments over the sector area. The ultrasonic beams transmitted are focused around predetermined transmit focal points and the transmit aperture employed for each transmission is determined by a transducer sensitivity criterion applied to the focal point. Means are provided for delaying signal components received from the beam directions so that the sum of the components will form a coherent echo signal. Means are provided for dynamically focusing received signal components by dynamically focusing received signal components by dynamically varying the sampling frequencies of laterally disposed signal components, and the receive aperture is dynamically varied in correspondence with the number of array elements which satisfy a sensitivity criterion at different depths of field.

摘要： An array of ultrasonic transducer elements receives signals to form beams simultaneously from a plurality of beam directions. The echo signals received by each transducer element are sampled in response to two or more interleaved sampling signal sequences, each of which is timed to begin at the initial time of arrival of echo signals from a unique spatial line. Each sampling signal sequence thereby produces signal samples associated with a given line. The stream of interleaved signal samples from each transducer element are separated in correspondence with each sampling signal sequence, and signal samples from corresponding separated sequences from the transducer elements are summed to form coherent signals corresponding to spatially separate ultrasonic beams.

摘要： A method and apparatus are provided for interpolating image lines from ultrasonically obtained scanlines of an image region. The interpolated lines are preferably formed one-quarter and three-quarters of the distance between each pair of received scanlines by combining weighted samples of the adjacent scanlines in proportion to their distances from the interpolated lines. The received scanlines are preferably formed by a beamformer which samples the received lines at quadrature phases of the scanhead center frequency and filters the samples by combining successive samples of a related phase. The image lines are scan converted by computing a grid of weighted values between each pair of image lines, and using the closest value for each pixel in the ultrasound image.
