Abstract: 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.

Abstract: In a method of compounding an ultrasound image, ultrasound signals having a transmission frequency are transmitted to a target object at a predetermined steer angle. Then, signals reflected by the target object are received. Based on the received signals, an image frame is formed. By repeating the above steps with different transmission frequencies, two or more image frames are obtained. The obtained image frames are then combined to provide a compound ultrasound image. The steer angle varies based on the transmission frequency.
