Elastic data such as the distortion and elastic moulds of a tissue of a subject (1) at measurement points of a cross-sectional portion of the subject is determined according to ultrasonic tomography data measured by applying a pressure to the tissue of the subject (1). An elastic image of the cross-sectional portion is created from the elastic data and displayed. The distribution of the elastic data such as the distortion and elastic modulus of the region of interest ROI set in the elastic image is displayed with a histogram. Hence, in addition to the information on the elasticity of the tissue graded with hue of brightness, new quantitative information reflecting the tissue properties is provided to support examination of a tissue.
Description
Ultrasonic diagnostic device technical field The present invention relates to an ultrasonic diagnostic apparatus capable of providing users with other quantitative information related to tissue elasticity in addition to elasticity images generated by measuring the elasticity (hardness or softness) of living tissue by applying pressure to a subject. information to support accurate diagnosis. Background technique In the technical field of ultrasonic diagnostic apparatuses, as described in Patent Documents 1 and 2, etc., a method has been proposed in which pressure is applied to the subject by the ultrasonic transmitting and receiving surface of the ultrasonic probe manually or mechanically. The displacement of each part of the living body is obtained by correlating the received ultrasonic signals before and after in time series, and elastic data on tissue elasticity is obtained based on the obtained displacement, and the elastic data is visualized. In addition, as tissue el...
