An image sensor includes a scintillator comprising a substrate covered with a layer of luminescent material, the layer of luminescent material comprising a first side in contact with the substrate and a second side, the surface of which has asperities, separated by interstices, a detection radiation emerging from the second side of the layer of luminescent material when the luminescent material is illuminated by a probe radiation through the substrate, characterized in that the second side of the layer of luminescent material is covered with a film of a coating material partially absorbing the detection radiation, and moulding itself to the asperities of the surface of the second side of the layer of luminescent material.
