title: Technical note: the efficacy of megavoltage imaging in the radical radiotherapy of non-small cell lung cancer.
abstract: Megavoltage imaging (MVI) has been used to obtain digital images of treatment fields during therapy for non-small cell lung cancer. Tumours were seen in all 33 cases studied and in three cases MVI was used to improve the set-up. It is concluded that in the setting of radical radiotherapy for non-small cell lung cancer this is an appropriate technique for the verification and correction of field position and is an aid to quality assurance.
