In this kind of study, the image analysis has an important role to obtain crucial information about blood rheology. The presence and physiological characteristics of other cell types are also of great clinical relevance.
In microcirculation, the study of red blood cells (RBCs) flowing in microvessels and microchannels and the study of the cell-free layer (CFL) thickness in different microchannels geometries are very important to get a better understanding of the blood rheological properties and disorders in microvessels in a fast and accurate way. Other approaches for blood flow studies are particle illumination photography, laser doppler velocimetry, fluorescent cytometry and computer fluid dynamics.
However, most in vivo measurements contain physiological fluids with high concentrations of blood cells and as a result, the amount of tracer particles captured within the fluid is often very low. Some studies have also combined PIV with ultrasounds (Echo-PIV). The micro-PIV technique is one of the best suitable methodologies to study blood flow phenomena in microcirculation. One of the most reliable ways to measure velocity fields in microcirculation is using Eulerian methods, such as the conventional micro-particle image velocimetry (PIV) or the confocal micro-PIV. Other techniques have been developed and combined to improve the acquisition and image processing. However, the technique requires long acquisition times and has low resolution. One of the first techniques used for the study of flow patterns was the phase-contrast magnetic resonance imaging (PC-MRI). Therefore, a detailed study of blood flow patterns and blood cells flowing in microvessels, microchannels and organs-on-chip is essential to provide a better understanding of the blood rheological properties and disorders in microcirculation. Additionally, a comparison analysis between manual and automatic methods was performed.īlood flow in microcirculation is crucial for the normal function of tissues and organs. Concerning automatic image analysis methods for individual RBCs tracking and to measure the well known microfluidic phenomena cell-free layer, two developed methods are presented and discussed in order to demonstrate their feasibility to obtain accurate data acquisition in such studies. For this reason, it is crucial to develop image analysis methods able to obtain the data automatically. Most of the past blood flow experimental data have been collected and analyzed by means of manual methods, that can be extremely reliable, but they are highly time-consuming, user-intensive, repetitive, and the results can be subjective to user-induced errors. For this purpose, the current methods used for tracking red blood cells (RBCs) flowing through a glass capillary and techniques to measure the cell-free layer thickness in different kinds of microchannels will be presented. This work shows different ways to process the images which contain various blood phenomena happening in microfluidic devices and in microcirculation. Set the xy (fig.1-27) and z (fig.1-28) calibration values as well as the time interval value (fig.1-26) in the appropriate option boxes.In blood flow studies, image analysis plays an extremely important role to examine raw data obtained by high-speed video microscopy systems.
