Abstract

An apparatus for reading information stored in a memory phosphor has a detecting device with an array of radiation-sensitive surface segments which during a pre-settable integration time interval receive a secondary radiation emitted by the memory phosphor. The apparatus includes a controller device that sets the integration time interval dependent on an amount of secondary radiation that was received at a preceding time. The controller device can also connect the radiation-sensitive surface segments into groups whose size depends on the amount of secondary radiation that was received at a preceding time.
