Ultrasonic imaging using Doppler effect caused by a moving transducer

Research output: Contribution to journalConference articlepeer-review


An imaging method using the Doppler effect is proposed in this paper. An object is illuminated by a sinusoidal wave from a linearly moving transducer. The frequency components of the reflected wave could be considered to be projections along lines at the corresponding angles. One can reconstruct images by applying the conventional CT (computerized tomography) algorithm to the projections thus obtained. The theory is derived, and it is confirmed by numerical simulation and experiment.
