[Site resolution study of venous outflow velocity and capacity by imaging plethysmography systems].
Two imaging systems designed for plethysmography purposes are used to investigate venous capacity as well as maximum venous outflow. A series of pictures of the extremity are taken during a subsystolic blood obstruction. As a result, capacity as well as maximum outflow can be plotted as locally resolved profiles alongside the axis of the extremity. The advantage of the new method compared to conventional plethysmography is discussed.
