摘要： There is provided an ultrasound system for forming strain images by decreasing decorrelation of receive signals, which vary with time or space. More specifically, the decorrelation between the receive signals obtained without and with applying stress to a target object is reduced to decrease an error, which occurs during the calculation of a delay. Also, a center frequency, which varies with depth of a target object, is compensated to form the strain image.

摘要： There are disclosed embodiments for forming an enhanced elastic image in an ultrasound system. An elastic image of a target object may be formed by scanning N scan lines. A control unit divides the N scan lines into M scan lines groups by using an acquisition period necessary for transmitting and receiving ultrasound signals to acquire ultrasound data. An ultrasound data acquiring unit transmits ultrasound signals to a target object and receives the ultrasound signals reflected from the target object at a predetermined transmission/reception sequence for each of the M scan line groups. This forms ultrasound data corresponding to each of the M scan line groups while a pressure is applied to the target object. An elastic image forming unit forms at least one sub elastic image corresponding to each of the M scan line groups based on the ultrasound data. The elastic forming unit sums M sub elastic images corresponding to the respective M scan line groups to thereby form an elastic image of the target object.

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.
