Abstract:
1. An ultrasound system for forming an elastic image of a target object, comprising: an input unit operable to allow a user to input an acquisition period representing time duration necessary for transmitting and receiving ultrasound signals to acquire ultrasound data; a control unit operable to divide N scan lines into M scan line groups by using the acquisition period and to determine a transmission/reception ordered sequence of the respective M scan line groups, wherein N and M are a positive integer and N is greater than M; an ultrasound data acquisition unit operable to perform plural transmissions/receptions of ultrasound signals to/from a target object with a pressure applied thereto for the M scan line groups in the transmission/reception ordered sequence thereof to thereby form a plurality of ultrasound data corresponding to each of the M scan line groups, wherein each of the plural transmissions/receptions is performed within the acquisition period; and an elastic image forming unit operable to form at least one sub-elastic image corresponding to each of the M scan line groups based on the ultrasound data, the elastic forming unit being further operable to sum the M sub-elastic images corresponding to respective M scan line groups to thereby form an elastic image of the target object.
