1. An ultrasound diagnosis apparatus for analyzing a contrast enhanced ultrasound image with respect to an object to which an ultrasound contrast medium has been administered, the contrast enhanced ultrasound image being obtained by transmitting ultrasound waves to the object and receiving echo signals reflected from the object, the ultrasound diagnosis apparatus comprising:

  • a processor configured to;

    acquire a time intensity curve representing an intensity value of a region of interest (ROI) of ultrasound image frames and a fitting curve representing a tendency of the time intensity curve according to a preset mathematical model,calculate a difference between the time intensity curve and the fitting curve for each of the ultrasound image frames, anddetermine a defective frame related to a movement or a change in size of the object in the ROI from among the ultrasound image frames when the calculated difference exceeds a threshold value for each of the ultrasound image frames; and

    a user input interface configured to display a graphical user interface (GUI) related to the defective frame.
