Phase imaging and myocardial performance

摘要: A method and system for monitoring performance of a heart includes forming time series frames echocardiographic data. The may be systolic interval, but longer intervals are also possible. the have sets corresponding data points with respect to specific sites patient's heart. For each set points, domain signal as function selected scalar is determined, thereby yielding which varies frame-to-frame variations scalar. has physiological significance contractile state or motion myocardium. Mean squared speed, root mean rate change, integrated backscatter, correlation area, magnitude suitable scalars. signal, phase angle obtained assign pixel value an image point. values utilized generate either gray-scale two-dimensional cardiac performance.
