[Radiation exposure of the lens during CT of the orbital area].
The exposure of the lens to irradiation in CT examination of the orbita was determined in a total of 80 patients via thermoluminescence dosimetry. Depending on a wide variety of parameters, exposures between 6.5 and 75 mGy were found with a mean of 28 mGy. By analysing the influence values thickness of layer and mAs product, suggestions for optimising orbita CT examinations are evolved.
