    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: 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: An embodiment for adaptively performing persistence processing on elastic images in an ultrasound system is disclosed. An ultrasound data acquisition unit sequentially acquires a plurality of ultrasound data frames based on ultrasound echo signals reflected from a target object by repeatedly applying and releasing stress to/from the target object. A processing unit calculates inter-frame displacements of the frames between the ultrasound data frames to form elastic images. The processing unit adaptively performs persistence processing on the elastic images in consideration of application or release of the stress to/from the target object.

    摘要: Embodiments for forming elastic images in an ultrasound system are disclosed. In one embodiment, a Tx/Rx unit repeatedly transmits/receives an ultrasound beam along scan lines in a target object to output receive signals. An image processing unit forms a plurality of consecutive ultrasound images based on the receive signals and set a center of the target object on each of the ultrasound images. The image processing unit further sets radial scan lines in radial directions with respect to the center on each of the ultrasound image and reconstructs the ultrasound images such that the radial scan lines are in parallel with each other to form reconstruction images. An elastic image forming unit forms an elastic image based on the reconstruction images.
