title: [Irradiation of the para-aortic ducts. Presentation of an radiation technic with a largely fixed patient's position].
abstract: An irradiation planning program has been developed at the Radiologic University Hospital of Graz which allows an interactive optimization of the energy dose distribution of a Co-60 radiation. This program is running in a minicomputer of type DEC PDP-11/34 under the operation system RSX-11. With the aid of this system, a technique has been developed for irradiating the para-aortic lymph canals which complies with theoretical as well as practical optimization criteria. These optimization criteria are defined, and the usefulness of this irradiation technique is compared with a conventional method and demonstrated on the clinical example.
