This article introduces a new technique for accurate verification of therapy treatment sites with radiographs. It can be used not only on most linear accelerators, but also on cobalt treatment units, with slight variation in exposure technique. It can eliminate the poor image detail presently seen and accepted at various therapy instiutions with a new method of quality control.
