Experimental setup for ultrasound imaging.
Fig 2.
Ultrasound images at each tunnel level (distal and proximal) for a representative male and female subject.
The images reflect the selection made in the custom LabVIEW code for the traced TCL (solid line) and the landmark of interest, specifically the hook of hamate (H), ridge of the trapezium (T), pisiform (P), and scaphoid (S).

The (a) arch width and height, (b) palmar bowing index, (c), arch area, and (d) normalized arch area at the two tunnel levels (distal and proximal) for the two sexes (female and male). * p<0.05.
