ULTRASOUND DIAGNOSTIC DEVICE

摘要

An ultrasound diagnostic device enabling accurate measurement of elasticity information. An ultrasound diagnostic device includes an ultrasound probe, a tomographic image generating means for generating a tomographic image from RF frame data on a cross-sectional portion of a subject obtained from the ultrasound probe, an elasticity information calculating means for obtaining the strain and/or elastic modulus of the tissue in the cross-sectional portion from the RF frame data, an elastic image generating means for generating an elastic image in the cross-sectional portion from the strain and/or elastic modulus obtained by the elasticity information calculating means, and a display means for displaying the tomographic image and/or the elastic image. The ultrasonic diagnostic device comprises a setting means for setting a first movement reference point and a second movement reference point on the tomographic image and/or the elastic image, and a measurement means for causing the first movement reference point and the second movement reference point to follow the pulsation of the subject and measuring the length of a line segment formed by the first movement reference point and the second movement reference point, and causes the display means to display elasticity information based on the length of the line segment and the strain and/or elastic modulus.
