IMAGE DATA PROCESSING SYSTEMS

摘要

This invention generally relates to methods, apparatus and computer program code for processing data captured from imaging systems, in particular pulse-echo imaging systems such as ultrasonic imaging systems, in order to determine deformation data for an imaged object. A method of processing at least one-dimensional image data captured by an imaging technique to determine deformation data defining an at least one dimensional deformation in an imaged object, the method comprising: inputting first and second sets of said image data corresponding to different deformations of said imaged object, each said set of image data comprising imaging signal data for an imaging signal from said object, said imaging signal data including at least signal phase data; and determining, for at least one point in said first set of image data, a corresponding displacement for said point in said second set of image data to provide said deformation data; and wherein said corresponding displacement determining comprises: initialising a value of said displacement to provide an initial current value for said displacement; determining an adjusted value for said displacement to provide said corresponding displacement, said determining of an adjusted value comprising: determining an average of differences in signal phase between corresponding positions in said first and second sets of image data, said corresponding positions being determined by said current value of said displacement; and using said average to determine said adjusted displacement value.
