Abstract:
The gamma index pass rate (%GP) of 384 helical Tomotherapy pre-patient quality assurance, acquired with ArcCHECK, is presented, analyzed, and correlated to plan characteristics. Average %GP was higher than 90% and correlated strongly with gamma method, irradiated length, pitch, maximum dose to diodes, and dose per fraction.
