Patent number: 8172756Abstract: 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.

Publication number: 20110137165Abstract: 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.Type: ApplicationFiled: August 7, 2009Publication date: June 9, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Cecile Dufour, Olivier Gerard, Thomas Gauthier

Publication number: 20110077515Abstract: 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.Type: ApplicationFiled: May 20, 2009Publication date: March 31, 2011Inventors: Olivier Gerard, Thomas Gauthiera, Cecile Dufour
