متن کاملA simple approach of three-isocenter IMRT planning for craniospinal irradiation
PURPOSE To develop a new IMRT technique to simplify the process and improve efficiency in radiotherapy treatment planning for craniospinal irradiation (CSI) treatment. METHODS Image data of 9 patients who received CSI treatment in 2012 were used, the prescription was 36Gy in 20 fractions. Two treatment plans were created for each patient, one was with the new technique called three-isocenter ...
متن کاملPractical dose delivery verification of craniospinal IMRT
Craniospinal irradiation (CSI) using IMRT allows dose sparing to organs-at-risk (OAR) whilst conforming the dose to the target volume. Due to the complexity of treatment involving several isocenters, the dose distribution created by the inverse-planned segmented fields must be verified prior to treatment. We propose and test methods to verify dose delivery using commonly available dosimetry equ...
متن کاملMethod to plan, administer, and verify supine craniospinal irradiation
Craniospinal irradiation remains an important technique in the management of malignancies of the central nervous system. It is technically demanding, with potential for treatment field overlap or gaps to yield unacceptable dosimetric heterogeneity. A method to accurately simulate and verify the three-field junction is described. We use a comfortable supine position to minimize patient movement....
