Abstract

Ultra micro angiography (UMA) can effectively improve the sensitivity and spatial resolution of blood flow imaging. To further meet the clinical requirements of quantitative measurements for microvascular imaging, this article demonstrated technical features and performance verification results of the microflow quantitative analysis function, which was developed based on the UMA function. This article provided preliminary validation of the measurement of Synchronous Arbitrary Gate-PW (SAG-PW) using a Doppler flow phantom and a moving string phantom. The Doppler flow phantom results demonstrated that the SAG-PW measurement values were close to the traditional PW results, and the average error of multiple sets of measurement results under different conditions was 3.9%. The results of SAG-PW and PW were strongly linearly correlated, with the slope and correlation coefficient approaching 1. The results of the moving string phantom demonstrated that the relative errors of TAMean and SAG-PW with different phantom set values were within 10%.

同步任意门- pw多普勒超声微血管成像的研制及初步验证

超微血管造影（UMA）可以有效提高血流成像的灵敏度和空间分辨率。为进一步满足临床对微血管成像定量测量的需求，本文展示了在UMA功能基础上开发的微流量定量分析功能的技术特点及性能验证结果。本文对同步任意门- pw （SAG-PW）的多普勒流模和动弦模测量进行了初步验证。多普勒流模结果表明，SAG-PW测量值与传统PW结果接近，不同工况下多组测量结果的平均误差为3.9%。SAG-PW与PW结果呈强线性相关，斜率和相关系数接近1。运动弦幻体实验结果表明，不同幻体设定值的TAMean和SAG-PW的相对误差在10%以内。
