Doppler blood velocity assessment based on image analysis of video-tape-recorded image data

A novel method for a fully automated determination of maximum blood velocity curves in Doppler ultrasound flow diagrams is reported. The method bases on VCR-recorded image sequences and hence uses an image processing scheme. Time-sequences of flow diagrams are evaluated and a chronological sequence of cardiac cycles is extracted. The cardiac cycles are numerically evaluated and the results in form of the peak velocity and the velocity-time-integral are reported.
