Abstract :
A method for the verification of accuracy of patient set-up during delivery of serial tomotherapy (ST) is presented. Analysis of 156 portal films taken during 132 fractions on eight patients enabled variation in daily setup to be quantified. It is concluded that daily portal verification of patient position is essential for accurate delivery of ST
