Comparison of rigid and deformable registration through the respiratory phases of four-dimensional computed tomography image data sets for radiotherapy after breast-conserving surgery.

Abstract The aim of this study was to compare the geometric differences in gross tumor volume (GTV) and surgical clips propagated by rigid image registration (RIR) and deformable image registration (DIR) using a four-dimensional computed tomography (4DCT) image data set for patients treated with boost irradiation or accelerated partial breast irradiation after breast-conserving surgery (BCS).

AB  - BACKGROUND: The aim of this study was to compare the geometric differences in
      gross tumor volume (GTV) and surgical clips propagated by rigid image
      registration (RIR) and deformable image registration (DIR) using a
      four-dimensional computed tomography (4DCT) image data set for patients treated
      with boost irradiation or accelerated partial breast irradiation after
      breast-conserving surgery (BCS). METHODS: The 4DCT data sets of 44 patients who
      had undergone BCS were acquired. GTV and selected clips were manually delineated 
      on end-inhalation phase (CT0) and end-exhalation phase (CT50) images of 4DCT data
      sets. Subsequently, the GTV and selected clips from CT0 images were transformed
      and propagated to CT50 images using RIR and DIR, respectively. The geometric
      differences in GTV and surgical clips from DIR were compared with those of RIR.
      RESULTS: The mean Dice similarity coefficient (DSC) index was 0.860 +/- 0.042 for
      RIR and 0.870 +/- 0.040 for DIR for GTV (P = .000). The three-dimensional
      distance to the center of mass (COM) of the GTV from RIR was longer than that
      from DIR (1.22 mm and 1.10 mm, respectively, P = .000). Moreover, in the
      anterior-posterior direction, displacements from RIR were significantly greater
      than those from DIR for both GTV (0.70 mm and 0.50 mm, respectively) and selected
      clips (upper clip, 0.45 mm vs 0.20 mm; inner clip, 0.55 mm vs 0.30 mm; outer
      clip, 0.40 mm vs 0.20 mm; lower clip, 0.50 mm vs 0.25 mm) (P = .000). However, in
      the left-right and superior-inferior directions, there were no significant
      displacement differences between RIR and DIR for GTV and the selected clips (all 
      P > .050). CONCLUSION: DIR can improve the overlap for GTV registration from CT0 
      to CT50 images from 4DCT scanning. Furthermore, DIR is superior to RIR in
      reflecting the displacement of GTV and selected clips in the anterior-posterior
      direction induced by respiratory movement.
