Abstract

3D evaluation algorithm instead of 2D evaluation method of clinical dose verification is highly needed for dose evaluation in Doseguided Radiotherapy. 3D evaluation algorithm of three evaluation methods， including Dose Difference， Distance ToAgreement and γ Analysis， was realized by the tool of Visual C++ according to the formula. Two plans were designed to test the algorithm: plan 1 was radiation on equivalent water using square field for the verification of the algorithm’s correctness; plan 2 was radiation on the emulation head phantom using conformal field for the verification of the algorithm’s practicality. For plan 1， the dose difference， in the tolerance range has a pass rate of 100%， the DistanceToAgreement and γ analysis was of a pass rate of 100% in the tolerance range，and a pass rate of 99±1% at the boundary of range. For plan 2， the pass rate of algorithm were 88.35%， 100%，95.07% for the three evaluation methods， respectively. It can be concluded that the 3D evaluation algorithm is feasible and could be used to evaluate 3D dose distributions in Doseguided Radiotherapy.
