title: Port film dosage in radiation therapy.
abstract: Portal verification has led many radiation therapy departments to implement policies of taking weekly port films for every patient. This has caused some to question the impact of port film dosage, once considered negligible. Using clinical data from 100 patients, this article examines the impact of port film dosage and offers suggestions for documentation and alternatives for decreasing dosages.
