Figure 3

Example of pennation angles of the superficial compartment plotted on a 3 dimensional representation of the aponeurosis for 2 different days. Note the overall similarity of pennation angles. Grey values indicate the location where either no fiber was tracked or a tract fiber was determined to be erroneous. The subject depicted did not show the best similarity in pennation angle, but showed a characteristic pattern in the posterior portion of the aponeurosis that was present in all four measurements. The anterior side of the aponeurosis is located on the left.
