The aim of the study was to find the most balanced plan with an optimal combination of planning parameters in helical tomotherapy (HT) for bilateral breast irradiation by evaluating dosimetric indices and time factors. In particular, we investigated the best combination of field width (FW), pitch, and modulation factor (MF). A total of 90 plans (18 plans for each patient) was created in this study, with different combination of planning parameters (FW 2.5 cm [F1] and 5 cm [F2]; pitch 0.215 [P1], 0.287 [P2], and 0.43 [P3]; and MF 2.0
