title: [Rotational irradiation with a centrally placed block].
abstract: A rotational field technique with a central placed block generates nearly circular isodoses with a pronounced minimum in its center, comparable with a cone-shaped mountain with a crater. The shape of both, mountain and crater, can be effectively varied by means of block size, field size, rotational angle and by superimposing two different types of rotational fields. One application of this radiation technique is the myelon-sparing treatment of the neck, another one the percutaneous completion of an intracavitary pre-radiation in the case of a gynecologic cancer.
