基于FPGA的超声动态聚焦数据整序设计

现有模拟整序折叠技术,对超声信号有衰减,而且在彩超中难以实现声束偏转。该文提出一种实现动态聚焦数据数字整序的设计方法。数字整序由两部分组成,即采用乘法器实现的位整序和用开关选择实现的字节整序。结果表明,在满足设计要求的同时,占用资源较少。

Ultrasonic Dynamic Focus Data Reordering Design Based on FPGA

The existing analog reordering and folding technology has the following 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.
