Figure 1. Ultrasound images of nerves in popliteal fossa.
Longitudinal ultrasound image of tibial nerve (TibN) in the popliteal fossa (A). Three areas of interest (AOI) are indicated by the rectangular boxes and were used for cross-correlational analysis for quantifying longitudinal excursion. Transverse plane ultrasound images of TibN and CFibN in the popliteal fossa (B). Directional orientation is presented in legends on the right. Skin/fascia represents the location of the skin and subcutaneous layers in the popliteal fossa. White bar in bottom right of images represents 5 mm.
