The Optimization of Ultrasound System Doppler Velocity Range Using Hybrid Control

Search this article

Abstract

We developed a technique to control the velocity range and offset of ultrasound Doppler images based on the histogram of Doppler auto-trace waveforms for the purpose of easy operation in clinical use. Conventional techniques are un-stable in the presence of poor Doppler signal or aliasing. We developed a new system based on hybrid control. We compared the performances with the conventional system by simulation. The stable response to various state changes assumed in normal clinical application was obtained.
