摘要： Even when a region of interest (ROI) is changed on a frozen image, an elasticity image of ROI after the change can be displayed without executing re-measurement. An ultrasonic diagnostic apparatus 1 has a control unit 110 having a first ROI setting unit 38 and a second ROI setting unit 39. When ROI is set by the first ROI setting unit 38 of the control unit 110, an elasticity information calculating unit 32 sets an area larger than ROI as a calculation area, calculates distortion, elasticity modulus, etc. of a tissue corresponding to each measurement point on a tomographic image of the calculation area, generates elasticity information based on the distortion, the elasticity modulus, etc., and outputs the elasticity information to an elasticity information storing unit 33. The control unit 110 changes the position/size of ROI by the second ROI setting unit 39 under a state that the frozen image is displayed. The elasticity image constructing unit 34 reads the elasticity information corresponding to the changed ROI from the elasticity information storing unit 33, forms an elasticity image of the changed ROI and displays it on an image display unit 26.

摘要： An elastic image suitable for diagnosis is easily acquired without depending on the examiner's pressure technique. The displacement of tissue in a tomographic portion of an object is measured on the basis of a pair of RF signal frame data items regarding the tomographic portion, which are obtained at different times by transmitting and receiving an ultrasonic wave to and from the object (b). The average displacement of each beam line (d0 to dn) of an ultrasonic wave is calculated (c), and a displacement gradient (50) in the scanning direction of an ultrasonic probe is calculated on the basis of the displacement average (d). A correction coefficient (52) with respect to the displacement of each beam line is calculated on the basis of the calculated displacement gradient (e), and the displacement distribution measured on the basis of the calculated correction coefficient is corrected (f). In this manner, even if the object is pressed by an ultrasonic probe inclined along the scanning direction, an elastic image generated by pressing the object with the ultrasonic probe not inclined along the scanning direction can be generated in a pseudo manner by correcting the displacement distribution on the basis of the correction coefficient.

摘要： An ultrasonic diagnostic apparatus and ultrasonic transmission/reception method that can acquire high-definition 3D elastic images and are very easy to use. A transmission/reception unit can switch between first transmission/reception condition, under which elasticity frame data is acquired at a first definition, and second transmission/reception condition, under which elasticity frame data is acquired at a second definition which is higher than the first definition. A switching unit detects variations in the elasticity values in the elasticity frame data and switches the aforementioned transmission/reception conditions from the first to the second on the basis of the stability of said variations.
