Determination of detection depth of optical probe in pedicle screw measurement device.

In the IL phantom measurements and the bones experiments a decreasing trend of the slope profile was observed when the probe passed through the boundary of two-layer vertebra tissues, especially when the probe was within the detection depth away from the bottom layer surface, shown in Figure 6 (b, c, d, e) and Figure 7 (b, c, d, e).
