a
Corrected distance. The physical distance between pins has been adjusted to account for the difference in
sound speed between urethane and tissue.
b
Uncorrected distance. Sound speed does not affect horizontal distance measurements when using a linear
probe
c
Corrected distance. Sound speed will affect horizontal distance measurements when using a sector scan-
ning probe
