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： An ultrasonic diagnostic imaging system is described by which a first sequence of ultrasound images of an organ such as the heart is acquired at a first image acquisition rate. The first sequence preferably images a larger volume or area in which a region of interest is located. Then a second sequence of three-dimensional ultrasound images of a sub-volume covering a part of anatomy of interest in the first sequence is acquired at a second image acquisition rate which is greater than the first acquisition rate. A third sequence of three-dimensional ultrasound images of a reference sub-volume is acquired at the second image rate. The second and third sequences of three-dimensional images are compared, enabling a clinician to focus on synchronism defects in the anatomy of interest with more precision and with a faster acquisition time.

摘要： A system for visualizing a myocardium represented by a cardiac image comprises a resampling means and a visualizing means. The resampling means resamples the intensity levels at sampling points on a plurality of curved surfaces, each curved surface enclosing at least part of a heart cavity and zero or more of the plurality of curved surfaces and being enclosed by the remaining curved surfaces of the plurality of curved surfaces, the plurality of curved surfaces together covering a hollow region in the cardiac image, the hollow region comprising the outer cavity walls of a group of at least one heart cavity. The visualizing means is arranged for visualizing at least part of at least one of the plurality of curved surfaces, using resampled intensity levels obtained from the resampling means. The group of at least one heart cavity may be the left atrium alone. It may also be the complete heart.
