摘要： The present invention relates to an ultrasonic imaging system for evaluating and displaying a deformation of a body organ. A sequence of image data sets comprising at least a first image data set and a second image data set of echographic data is acquired. A motion vector field is calculated between image points of the second image data set and image points of the first image data set. A reference point is chosen within or outside the first and second image data sets. A first scanline is defined, which comprises said reference point. A motion vector of an image point is projected onto the defined first scanline, which provides a projected tissue velocity along the first scanline. The projected tissue velocity is used for evaluating a ID component of a deformation of the body organ at the image point along the direction of the first scanline. Such a ID component of a deformation of the body organ, for example a strain rate or a strain, is further rendered in a graphical representation of the sequence of image data sets.

摘要： The invention relates to an ultrasonic diagnostic imaging method for determining propagation parameters of transient shear wave front, comprising steps of forming transient shear waves in a tissue (5), acquiring ultrasonic image data (S,S*) of the tissue, along image lines (l), during a time delay (TSW) for a transient shear wave front to propagate over a depth (z) in said tissue, estimating the tissue velocity (V) for each line, constructing a tissue velocity image sequence [I(V)] from the ultrasonic data (S,S*) and the tissue velocities (V) on the lines, and deriving the velocities (CSW) of the shear wave front at instants of the sequence. Tissue parameters such as elasticity are then calculated from said front velocity. The invention also relates to an ultrasonic diagnostic imaging system having processing means (100, PROCESSING1, PROCESSING2) for carrying out this method. The processing means may be a computer program product having instruction to this end.
