定向式“多普勒流速描记器”可对含有相当粒子数的液流描出其流速曲线。其所能描出最小内径的血管内血流的能力,将为决定临床应用范围的一个方面;能否在大液流邻近测出另一小液流,则为开展临床应用的又一个方面。为此,进行了动物实验。 Directional “Doppler flow trackers” can plot the flow rate curve for liquids that contain a relatively large number of particles. The ability to profile the smallest intravascular volume of blood flow will be one aspect of determining the range of clinical applications. Whether or not to measure another small flow adjacent to a large flow is another aspect of clinical application. For this purpose, animal experiments were conducted.
