[Hyperfractionation--a new challenge for medical electron linear accelerators?].
In radiotherapy to an increasingly degree radiobiological aspects of the tumor behaviour during therapy are realized in daily routine. An example for this is the so called hyperfractionation of the total dose: that means multiple small fractions are applied. Doses of as low as circa 40 cGy per field are necessary. This investigation affects the constancy and the behaviour of the following beam parameters of various treatment units during the initial stage of operation (circa ten seconds): energy of bremsstrahlung, symmetry, flatness and proportionality of dose.
Spectral transmission characteristics of intraocular and aphakic contact lenses.
Of seven intraocular and 13 aphakic hard contact lenses evaluated for their transmission characteristics to near UV radiation, all intraocular lenses and 12 of 13 hard contact lenses showed high transmission peaks for UV radiation between 300 and 400 nm.
