Abstract
Motion due to breathing often results in up to several centimeters of target motion during treatment. There have been a few studies showing the dosimetric consequences of target motion during static and dynamic multileaf collimator-based IMRT delivery. However, no studies have been reported on breathing-motion induced dose errors in serial tomotherapy. It has been reported in the literature that even small misalignments in serial tomotherapy will result in large errors in dose delivery (25%/mm) where the individual serial deliveries (indices) abut.
