ABSTRACT:
In spite of optimum density on the film, tomography using automatic exposure control can produce exposures which have a less pronounced movement unsharpness than could be expected on the basis of the geometrical proportions. It was found that such effects always occur when the tube power resulting from the exposure control substantially deviates from the tube power initially adjusted. Therefore, means are provided which enable, in dependence of this difference, the exposure data to be changed for the next exposures of a series of tomographic exposures.
