Patent ID: 8900144

Claim:
A diagnosis apparatus comprising: a probe for transmitting an ultrasonic wave signal to a subject and receiving a response signal; a data generating unit for generating image data of a plurality of frames, based on the response signal; a reliability determining unit for grouping the plurality of frames into a plurality of sub durations, and determining whether the image data is reliable by estimating a motion of the probe based on difference values between frames included in the plurality of frames; a diagnosis unit for generating diagnosis data about the subject by using elastography, based on the image data; and a display device for displaying an image based on the image data and displaying a plurality of reliability indicators based on a reliability determination result of the reliability determining unit, wherein the plurality of reliability indicators have one-to-one correspondence to the plurality of sub durations, and each of the plurality of reliability indicators indicates reliabilities of a corresponding sub duration from among the plurality of sub durations.
