A typical application of perometer measurements is the observation of the volume development of extremities in time.
The following video example demonstrates that reproducible results can be achieved even over long periods of time. In this case, a patient was observed over 10 years. During the first 6 years the leg shows merely minimal variations in volume. Only in the 7th year of observation does a clear swelling in the thigh area develop. This swelling even increases in the following time. At the same time it is easy to see that in the calf area, the volume remains unchanged.

All 3d leg graphics were created with the Perometer software PeroScan. The final volume increase in the red marked area is 380 ml (18%) compared to the first measurement.
