在这项研究中，我们考虑了红细胞运动速度和红细胞运动之间的关系。许多测速仪通过跟踪流体中存在的示踪剂颗粒的运动来测量流体速度。通常，在激光多普勒测速中，在被测流体中加入适当密度和大小的种子颗粒，但在活体测量中这是不可能的。在血液中，红细胞被用作示踪粒子。然而，目前还不清楚红细胞的速度是否反映了实际的红细胞速度。因此，我们比较了蛇形流道中小鼠耳血管和含有示踪剂颗粒的水中血液的流速分布测量结果。比较的结果表明，红细胞运动的速度与血液的速度并不完全一致。这种差异是由于皮肤下条纹图案的变化造成的。然而，我们认为利用这些条纹变化来测量任何方向的红细胞速度是可能的。此外，我们还证实了用该方法得到的结果与用其他方法得到的结果是一致的。©2016日本电气工程师学会。作者：John Wiley&Sons，Inc.
In this study, we consider the relationship between red blood cell velocity and the movement of erythrocytes. Many velocimeters measure fluid velocity by tracking the movement of tracer particles present in the fluid. Generally, in laser Doppler velocimetry, seeding particles of suitable density and size are added to the fluid being measured, but this is not possible forin vivomeasurements. In the case of blood, erythrocytes are used as the tracer particles. It is unclear, however, whether the velocity of erythrocytes reflects actual red blood cell velocity. Therefore, we compare the results of flow velocity distribution measurements of blood in the ear vessels of mouse and in water containing tracer particles in a serpentine flow channel. Results of the comparison indicate that the velocity of moving erythrocytes does not correspond exactly to the velocity of the blood. The difference is due to the changes in the fringe pattern under the skin. However, we consider that it is possible to measure red blood cell velocity in any direction using these fringe changes. Moreover, we confirm that results obtained using the proposed method match those obtained using other methods. © 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
