title: The use of independent collimation in the treatment of Graves' ophthalmopathy.
abstract: Graves' ophthalmopathy is an infiltrative disease of the orbit and randomized trials show that radiotherapy should be the first treatment of choice. This article describes how linear accelerators with independent collimation can be used for setting up purposes, in place of lead blocks, to shield the lens. This benefits the patient and radiographer by being quicker, more accurate and easier to set up.
