Method and image pickup system for measuring an imaging radiation dose during pickup of a radiation image of a subject

A method for measuring an imaging radiation dose, comprising the steps of:

• emitting radiation from a radiation source, said radiation propagating in a propagation direction;
• detecting said radiation with a solid-state radiation detector which allows said radiation to penetrate therethrough and which has a transmission behavior which influences the radiation penetrating through said solid-state radiation detector;
• disposing a radiation sensor, comprised of a radiation detector on a semiconductor base, behind said solid-state radiation detector in said propagation direction, and detecting the radiation penetrating through said solid-state radiation detector with said radiation sensor and generating an output signal from said radiation sensor dependent thereon;
• and
• processing said output signal in a computer dependent on the transmission behavior of said solid-state radiation detector to determine an imaging radiation dose at a location in front of said solid-state radiation detector.
