Claim:
1. A detector device for detecting a primary radiation from a primary radiation source, the device comprising: a substrate having a first surface and a second surface; a scintillator configured to generate a converted primary radiation in response to incoming primary radiation; a photo detector configured to detect said converted primary radiation; a secondary radiation source configured to irradiate said scintillator with a secondary radiation to thereby produce a spatially more uniform response of the scintillator to said incoming primary radiation; said secondary radiation having a wavelength different from a wavelength of said incoming primary radiation; and a tertiary radiation source having a plurality of tertiary light emitting diodes located on the second surface of the substrate and configured to irradiate the scintillator with tertiary radiation which is different from the secondary radiation, wherein the photo detector is located on the first surface of the substrate and the secondary radiation source is located on the second surface of the substrate, and wherein the first surface of the substrate faces towards the scintillator and the second surface of the substrate faces away from the scintillator.
