Dynamic color Doppler extended field of view imaging

A new method for generating dynamic color Doppler extended field of view (EFOV) images is presented. The method derives an ECG waveform from the spatial average of Doppler velocity data from a series of co-planar ultrasonic images acquired by translating the probe in the azimuth direction. Translation and rotation parameters between successive images are estimated using speckle correlation of the B-mode data. The images corresponding to the same phase of the synthetic ECG are then combined using, these, motion parameters to form a color Doppler EFOV image. A series of these color Doppler EFOV images are generated corresponding, to, different cardiac phases. These images are then played back in a continuous loop over the B-mode EFOV image.
