title: A technique for the treatment of large irregular fields.
abstract: Each method of producing irregular shaped fields has its own particular advantage. This report describes one technique of irregular field production with minimal handling of the shielding material, tapered shielding to provide the greatest accuracy in the field shape, and rapid achievement of patient setup. The reproducibility of these fields is considered.
