Abstract
X-ray examination apparatus includes means for terminating an exposure at a dose determined, in part, by the value of the tube voltage and the characteristics of the intensifying screen in use. Means are provided to read screen-identifying markings on film cassettes and to adjust the turn-off dose level in response thereto.
