A Noninvasive 3D Body Scanner and Software Tool towards Analysis of Scoliosis

Figure 7

Optimality values (in logarithmic scale) are plotted for each CT data set. Filled bar indicates optimality values between the trajectories obtained from 2D X-ray image analysis and vertebral body analysis (SP1 vs. SP3), open bar indicates optimality values between the trajectories obtained from vertebral body analysis and the body contour line analysis (SP3 vs. SP2). Circle with solid line is the average of optimality between the SP1 vs. SP2 sets of trajectories and diamond with dotted line is the average of optimality between the SP3 and SP2 sets of trajectories. Missing bars correspond to cases for which the quality of the 3D surface scan was not good enough for a clear analysis.
