The optical system used to quantify the spatial growth of plasma clots on a tissue-factor-coated insert (thrombodynamics) (a) and the kinetics of contraction (retraction) of blood clots (b). On the left are images of cuvettes containing a growing (a) or contracting (b) clot and on the right are the output kinetics curves with the corresponding parameters.
