[Dosage of conservative therapy of the mammary carcinoma by means of opposing Co-60 wedge filter fields (author's transl)].

A method of measurement is described which allows to determine the maximum dose (tumor dose) for routine radiotherapy of the breast with opposing Co-60 wedge filter stationary fields. Furthermore it could be demonstrated that--independently of the form of the mamma--a sufficiently precise dosage can also be achieved by means of a simple calculation. For this purpose one must only know the base (= distance of the dorsal field marks on the skin) and the irradiation time for the dose to be applied into the depth dose maximum of a rectangular stationary field without filter.
