摘要： In an ultrasound imaging system (UIS), an image capturing arrangement (ICA) captures a sequence of ultrasound images (IMS) of a body (BDY) while an object (NDL) is introduced into the body. A displacement detector (DD) generates a map of displacement indications (DM) from the sequence of ultrasound images. A displacement indication relates to a particular portion of the body and indicates a displacement that the portion has undergone. An object locator (OL) provides an indication (OLI) relating to the location of the object in the body on the basis of the map of displacement indications.

摘要： Elasticity variation within biological tissue is often correlated with its pathology. Variation of elasticity can be assessed by specific ultrasound acquisition sequences during which pressure is applied. The tissue motion and deformation during those sequences is correlated to the tissue stiffness. The present invention describes a hybrid method that combines a real-time monitoring mode during acquisition and a non-real-time fine analysis after acquisition. This method allows early identification and fair assessment of pathology from elastographic analysis to obtain the best possible result for elastography assessment.

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.
