Paper Abstract

The capabilities of a pulsed photoacoustic technique for monitoring blood sedimentation and red blood cell (RBC) aggregation were tested in a cuvette in vitro. Diluted blood samples with concentrations of 40% and 60% were used. In addition, the effect of dextran (T500) was investigated with blood concentrations of 40% and 60%. Optical coherence tomography was used in parallel to visualize the sedimentation process. The results show that a 1 MHz acoustic transducer can be used to detect PA signals from blood in vitro during sedimentation, and the acoustic pulse delay is a good indicator for following the sedimentation process. Dextran greatly accelerated the sedimentation process.
