摘要：

The dynamic time warping approach is utilised to obtain a template fi om the left ventricular volume signal. The technique by performing shrinking and enlarging of the temporal axes of two waveforms, indicates the best non linear alignment between them. In this application this technique is used to track on a cycle-by-cycle basis the diastasis onset and offset thus allowing us to reliably measure temporal sub-intervals of the filling period.
