Abstract:
The existing analog reordering and folding technology has the fol owing problems:it cause the attenuation of the ultrasonic signal, and it is difficult to achieve beam steering in color doppler ultrasonic diagnostic instrument. This article proposes a design method to achieve digital reordering of dynamic focusing data. The digital reordering is composed of two parts, bit reordering which is implemented with multiplier and byte reordering using switch selection. The results show that it can meet the design requirements using fewer resources.
