Figure 2From: Evalution of surface-based deformable image registration for adaptive radiotherapy of non-small cell lung cancer (NSCLC)Patient individual voxel-based analysis of deformable image registration based on ROI extended (covering the GTV + 10 mm in superior-inferior direction but including the whole body contour in axial directions). Correlation-coefficients (CC) were calculated between the planning CT image and original/deformed follow-up CT image (mid-way and at the end of the treatment course).Back to article page
