Abstract
TiVi technology presents a high resolution, low speed methodology for imaging microcirculation. Recently, the TiVi system was adapted to produce a high speed system capable of analysing dynamic responses from human tissues at a frame rate of 30 frames per second. We present results based on this system by investigating dynamic responses such as arterial pulsations both from a controlled flow model and in vivo tissue sites. We also quantify the effects of sympathetic vasomotion, a biological effect which is evident in many tissue sites, and show that the effects of arterial pulsations and vasomotion on the resulting TiVi time traces are easily determined.
