PROBLEM TO BE SOLVED: To provide an ultrasonic image forming method for embodying an image by reducing the uncorrelation degree of an elastographic image signal to be changed by time or space. SOLUTION: The ultrasonic image forming method is the one for forming the image by reducing the uncorrelation degree between signals before/after compression through the use of an elastography, which is technique to measure the degree of stiffness in a tissue with a real-time ultrasonic medical image, so as to reduce a difference in delay time estimation. Especially, the method embodies the elastoraphic image by compensating the change of a center frequency to be changed by the depth of an object body and reducing the uncorrelation degree between the elastographic image signals for inducing a calculation error.
