Abstract :
Doppler velocity contour analysis has been hampered by uncertainty in determination of the contour. Current methods of contour determination are subjective and prone to observer dependent variations since they require manual tracing of the perceived contour. A computer-based method of Doppler velocity contour computation from the echocardiographic acoustic signal has been developed and is applied to the human transmitrai diastolic Doppler velocity profile.
