The ultrasound system and a method for forming an elastic image by using the Arfi

The ultrasound system and method of forming the elastic image are provided using the ARFI. The system and method, the first transmit ultrasound signals to a target object and receives ultrasound echo signals reflected from the target object to form a first received signal, using the first received signal to form a reference image, with respect to the reference image and a plurality of detecting an object, feature points, the predetermined transmission power (power) to a have a focusing the second ultrasound signals for applying stress to the target object on each of the boundary points of the reference image receiving an ultrasound echo signal to be transmitted and reflected from the target object to the target object and the second to form a received signal, the formation of ARFI (acpustic radiation force impulse) image using the second reception signal, a plurality of detecting the feature points of the target object for the ARFI image and detecting in the reference image and the ARFI image respectively using a plurality of boundary points and the transmission power and calculates the stress of the respective feature points, the elastic stress using the calculated To form an image.
