摘要

Purpose To report an implementation method and the results of independent brachytherapy dose verification software (DVS). Material and methods The DVS was developed based on Visual C++ and adopted a?modular structure design. The DICOM RT files exported from a?treatment planning system (TPS) were automatically loaded into the DVS. The DVS used the TG-43 formalism for dose calculation. A?total of 15 cervical cancer patients who underwent brachytherapy were retrospectively selected to test the DVS. Dosimetric parameters and ? analysis (0.1 cm, 5%) were used to evaluate the dose differences between the DVS and the TPS. Results Compared with the TPS dose, the ? pass rates of the dose calculated by the DVS were higher than 98%. For the clinical target volume (CTV), the dosimetric differences were less than 0.63% for D90% and D100%. For the bladder, rectum, and sigmoid, the agreement of D0.1cc, D1cc, and D2cc were within a?0.78% level. Conclusions With minimal human-computer interactions, the DVS can verify the accuracy of doses calculated by the TPS.
