Figure 2.

Qualitative evaluation of the algorithm performance. (A) Scatterplot of the DSC versus tumor volume (n = 60). The mean DSC is indicated with a horizontal red line. The ±1SD and ±2SD are indicated with blue dotted lines. (B) Axial µCBCT images showing (from left to the right) an unsegmented scan, the manual tumor segmentation, the automatic tumor segmentation, and the overlay of the manual and automatic segmentations. The first row shows an illustrative case with a high overlap, the second row shows a case with minimal overlap, and the third row depicts a case with medium overlap. The corresponding DSCs of each row in (B) are indicated in the scatterplot of (A) by the green, red and yellow markers.
