    摘要： Embodiments for providing a strain image in an ultrasound system are disclosed. In one embodiment, a processing unit sets windows on a pre-compression frame and a post-compression frame, and performs a correlation operation between the first and second frames within the windows to compute displacements for a third frame, wherein the processing unit selects at least one of previously set windows at an (N-i) th row by referring to current windows positioned at a N th row in an axial direction, computes an initial displacement based on displacements corresponding to the selected at least one of windows, and determines a range for moving the current window on the second frame in the axial direction based on the computed initial displacement.

    摘要： Embodiments for providing an elastic image are disclosed. In one embodiment, an ultrasound system comprises: an ultrasound data acquisition unit (110) configured to transmit and receive ultrasound signals to and from a living body to output ultrasound data corresponding to a plurality of frames while applying compression to the living body; and a processing unit (120) configured to extract frames from a (n-1) th frame to a (n-i) th frame on a basis of a n th frame, wherein n indicates an integer larger than one and i indicates a positive integer, detect an optimal frame for forming an elastic image among the extracted frames by using first displacement between the n th frame and each of the extracted frames based on the ultrasound data, calculate second displacement between the optimal frame and the n th frame based on the ultrasound data, and form the elastic image based on the second displacement.
