Impact of motion induced artifacts on automatic registration of lung tumors in Tomotherapy
Highlights • We aimed to validate a tumor-based registration of lung tumors in Tomotherapy. • We explored the effect of motion-induced MV-CT artifacts on automatic registration. • Registration errors were acceptable (within 1.3 ± 1.2 mm). • Only breathing period of 5 s induced more significant regis...
