Abstract
A planar image detector for electromagnetic rays producing an image for an examination subject has an active surface on a substrate with a matrix of radiation-sensitive pixel elements, and a radiation-sensitive sensor for generating control signals for an exposure control is arranged immediately next to the active area within the rays attenuated by the examination subject.
Claims15
A planar image detector for electromagnetic rays for producing an image from said electromagnetic rays, comprising:
- a substrate having an active surface formed by a matrix of radiation-sensitive pixel elements in an imaging procedure subject to exposure control, said active surface being adapted to receive radiation attenuated by an examination subject;
- and
- a radiation-sensitive sensor disposed immediately next to said active area and also adapted to receive said radiation attenuated by said examination subject, for generating a control signal for said exposure control dependent on said radiation attenuated by an examination subject incident on said radiation-sensitive sensor.
