title: [Further considerations on the basis of the Ellis-formula and its application (author's transl)].
abstract: Computational methods for the determination of normal tissue tolerance under various modes of dose fractionation are applied at many radiation therapy installations. The methods differ in details, but most are based on the Ellis-formula. A survey of the relevant quantities and relations is given in order to facilitate comparison of the various methods. The established equations which are applicable to regular fractionation are related to the generalization of the Ellis-formula which is also applicable to irregular fractionation modes.
