First Claim
1. An ultrasonic diagnostic device, comprising:
- an ultrasonic probe for transmitting/receiving ultrasonic waves to/from an object;
reception processing unit for receiving a reflection echo signal measured by the ultrasonic probe and generating RF signal frame data at a cross-sectional plane of a part to be diagnosed of the object;
displacement measurement unit for, on the basis of one pair of pieces of RF signal frame data having different states of pressing against a tissue at the cross-sectional plane, measuring displacements of the tissue at a plurality of measurement points of the cross-sectional plane and generating displacement frame data;
elasticity information calculation unit for, on the basis of the generated displacement frame data, calculating pieces of elasticity information indicating hardness or softness of the tissue at the plurality of measurement points of the cross-sectional plane and generating elasticity frame data;
evaluation image generating unit for generating, as an image for evaluation for evaluating the degree of a disorder of the part to be diagnosed of the object, histograms of at least one of the displacements and the pieces of elasticity information of the tissue at the plurality of measurement points of the cross-sectional plane at different times; and
an image display which displays the histograms at the different times.
