ABSTRACT:
A transmitter transmits ultrasound signals towards a region to be imaged. The reflected ultrasound signals from the region are detected by a receiver. The transmitter and/or receiver is or are moved relative to the region to create Doppler phase shift. The time compression/expansion caused by the Doppler phase shift is dewarped by filtering in order to recover the amplitudes of the ultrasound signals reflected from different portions of the region for imaging.
