Platelet adhesion onto immobilized fibrinogen under different shear rate conditions with regard to the perfusion time (n = 29). 13 s^-1 and 50 s^-1 mimic venous flow and 1500 s^-1 arterial flow. Platelet adhesion between 15 sec and five min of perfusion increased five-fold at shear rate of 13 s^-1 and 14-fold at arterial shear rate of 1500 s^-1. Per each subject 3 flow experiments were conducted (13 s^-1, 50 s^-1 and 1500 s^-1). Finally 87 perfusion experiments were conducted. At each time point of perfusion (15 sec, 1 min and 5 min) a stack of 5 images was collected and analyzed.
