Patent ID: 8353831

Claim:
A diagnostic ultrasound system comprising: an ultrasound transducer for transmitting and receiving ultrasound waves to and from an object to be examined; transmitting means for supplying a driving signal to the ultrasound transducer; receiving means for processing a reception signal output from the ultrasound transducer; elasticity image imaging means for obtaining an elasticity image related to a body tissue of the object to be examined on the basis of a signal output from the receiving means; and displaying means for displaying the elasticity image, wherein the elasticity image imaging means includes compression state evaluating means for: obtaining compression data related to a compression state of the body tissue of the object to be examined, and determining that: a coordinate region with a magnitude of the compression data exceeding a threshold value is within an adequate compression range; and a coordinate region with a magnitude of the compression data not exceeding the threshold value is an inadequate compression range, wherein at least one of the adequate compression ranges and at least one of the inadequate compression ranges are displayed on the elasticity image, with a border between the adequate compression range and the inadequate compression range.
