From: Ultrasound-derived changes in thickness of human ankle plantar flexor muscles during walking and running are not homogeneous along the muscle mid-belly region

Figure 1

(A) Example ultrasound image of lateral gastrocnemius and soleus muscles, with each of the aponeuroses fit with the active shape model (yellow). The fit provided 19 points along each aponeurosis, separated by 32 pixels (2.75 mm). (B) Representation of the 20 point landmarks distributed along each aponeurosis shape model fit (coloured squares). Coloured vertical lines represent thickness measures recorded in soleus. The colour scheme is used in following figures to indicate the distal-proximal location of reported thickness measures.
