Abstract

See full text

An ultrasound diagnostic apparatus with which elastic modulus can be measured when measuring elastic modulus using shear wave generation. The ultrasound diagnostic apparatus includes an ultrasound probe that sends and receives echo signals, a strain-computing unit that receives an echo signal from the body by radiating a first displacement-detecting beam and computes strain information in a Region 1, a measurement position-selecting unit that selects a Region 2, within Region 1, based on the strain information, a displacement-generating unit that radiates a focused beam into the body and displaces the tissue, an elastic modulus-computing unit that receives an echo signal from the body by radiating a second displacement-detecting beam, detects the shear wave displacement that results from the focused beam, and computes the elastic modulus in Region 2, and a display unit that displays the strain image that is based on the strain information in Region 1 and the elastic modulus.
