Figure 2From: A comparison of dosimetric parameters between tomotherapy and three-dimensional conformal radiotherapy in rectal cancerTomotherapy significantly reduced the V 25Gy , V 22.5Gy, V 20Gy , V 17.5Gy , V 15Gy , and V 10Gy value of the small bowel as compared to 3D-CRT. However, the V5Gy value which had been associated with the low irradiation range of the normal tissue was not significantly different between the two modalities.Back to article page
