Abstract :
A new continuous dynamic focusing technique for ultrasound imaging is proposed. The conventional delay-sum-sampling process can be replaced by a sampling-sum process if the maximum delay time is less than the sampling interval. To extend the sampling interval effectively, second-order sampling is adopted.
