Figure 2
Locating accuracies were calculated using different methods. The results of the simulated X-ray projections are shown in (a) and the results of the simulated fluorescence images are shown in (b). Horizontal axes represent the numbers of fluorescence spheres contained in each fiducial marker. The purple lines with squares, red lines with circles and blue lines with triangles represent the accuracies of locating manually, locating automatically using actual positions and locating automatically using manual locating results as initial positions, respectively. |
