本文介绍的系统基于连续波多普勒效应和脉冲回波锁相跟踪相结合的方法.采用特殊结构的探头,消除了流速波束夹角对多普勒血流测量结果的影响;应用单片机控制系统,实现了血管管径、血流速度和血流流量的数字化实时定量测量。
The system introduced in this paper is based on the combination of continuous wave Doppler effect and pulse-echo phase-locked tracking. The probe with special structure is used to eliminate the influence of the flow beam angle on the measurement results of Doppler blood flow. By using SCM control system, Realize quantitative real-time measurement of blood vessel diameter, blood flow velocity and blood flow.
