[Patient dosage load with the vidio amplifier technique in pediatric radiology (authors transl)]

The desired reduction of dosage with the indirect technique compared with the close up is only obtained if the vidio amplifier (i.e. 50 muR/picture) is adjusted exactly, if the input potential of 60 kV is not exceeded, particularly for infants, and no high kV grids are used. An adjustable diaphragm in front of the camera with the adjustment of the vidio amplifier and with the electron-optical changeover from, for example 9" to 5", would result in an additional reduction in dosage.
