Abstract:
1. A method for automatically measuring, in an ultrasound system, synchronization of tissue motion and deformation, comprising: obtaining, from the ultrasound system, a data set of ultrasound samples representative of at least one of a left ventricle and a right ventricle, said data set comprising frames of said samples acquired over at least one heart cycle; obtaining a user input, to the ultrasound system, identifying a measurement feature relative to said at least one heart cycle; identifying a reference time within said frames of said data set; determining a search interval within said frames of said data set; analyzing each said sample in said frames within said search interval to determine a point in time when each said sample reaches said measurement feature; determining, for each said sample, a time delay between said reference time and the point in time at which each said sample reaches said measurement feature within said search interval; assigning at least one color, from a continuous range of colors, to each said sample based on said time delay for said corresponding individual said sample; and displaying a parametric image of said colors assigned to said individual samples for at least one said frame in said search interval to present an amount of synchronization between said samples in said frame.
