THIS communication describes a new and accurate method of treating malignant disease by radiation. The radiotherapeutic world is convinced that accuracy in dose delivery in adequate amounts to minimum volumes has largely been responsible for improved results in limited disease. Just as surgery has its complications and rare fatal accidents, so also does a proportion of radiation injuries have to be accepted at curative dose-levels. A high standard of accuracy in treatment does much to reduce injuries by limiting the volume of tissue exposed. This new method has been the logical sequence of development over the past twenty-five years, passing through four phases.
