Improvement of Horizontal Resolution by Doppler Image under Forced Vibration

Abstract:

Generally, cross range resolution of a B-mode ultrasonic image is restricted by a point spread function of the measurement system. Although various super-resolution techniques are proposed, it is difficult to significantly improve the resolution with low calculation burden. In this paper, we propose a novel super-resolution technique in which the Doppler B-mode image is measured under forced vibration in the region of interest. The numerical simulation is carried out to demonstrate the validity of the proposed algorithm. It is shown that the cross range resolution is 3 times narrower than the original one.
