Patent ID: 8546765

Claim:
A radiation detector pixel for x-ray radiation, comprising: a sensor device, and at least one readout amplifier, wherein the sensor device comprises at least one actuator device as an automatic sensitivity range controlling device for controlling a conversion of incoming electromagnetic radiation into electric output quantity; and wherein the at least one actuator device is adapted to allow a signal charge of a single exposure to be read out with at least two sensitivity ranges, by: shifting electric charges between a first capacitance and a second capacitance of the radiation detector pixel, and/or; selecting a high sensitivity range amplifier or a low sensitivity range amplifier of the radiation detector pixel; and wherein for each of the at least two sensitivity ranges, a ratio between the incoming electromagnetic radiation and the electric output quantity is continuous in an operational range, wherein the operational range refers to all operational points from zero until saturation; and wherein the at least one actuator device is implemented on the radiation detector pixel.
