Abstract: Objective To investigate the application value of conformal and intensity modulated(3DCRT + IMRT) field convergence technique for the craniospinal irradiation(CSI) of children. Methods Admitted from 2012 to 2015 in the First Affiliated Hospital of Xinjiang Medical University, 6 children under the age of 14 who were treated with CSI were selected.The field convergence techniques of three- dimensional conformal radiotherapy(3DCRT), 3DCRT + IMRT and intensity modulated radiotherapy(IMRT) were respectively applied to design plans. The uniformities of the dose distribution of target volume and normal tissue in the 3 plans were compared by using SPSS 17.0 software. Results The 3DCRT + IMRT field convergence technique was suitable for the CSI of children. For the evaluation of target volume, the conformity index of3 DCRT + IMRT field convergence technique was better than that of the 3DCRT field convergence technique, but slightly worse than that of IMRT field convergence technique. No significant differences were found in heterogeneity index among the three techniques. And the 3DCRT+IMRT field convergence technique combined the advantages of 3DCRT and IMRT on the protection of normal tissue. Conclusion The 3DCRT+IMRT field convergence technique is a good choice in the CSI of children, having unique advantages in the protection of normal tissue.
