Radiological detector structure comprising a mechanical protection housing having plural layers of rigid material with a layer of cellular material therebetween

A portable radiological cassette comprising:

• a scintillator capable of converting an incident x-ray into a light signal,
• a photosensitive slab capable of converting the light signal emitted by the scintillator into an electrical charge, the scintillator and the photosensitive slab forming a panel, the panel having a front face intended to receive the incident x-ray and a rear face opposite the front face,
• an electronic circuit board ensuring the conversion of the electrical charge into a digital image,
• a mechanical protection housing, wherein the panel and the electronic circuit board are disposed, comprising a top face and a bottom face;
• wherein the top face of the mechanical protection housing comprises:
• a first layer of rigid material,
• a second layer of rigid material, the second layer of rigid material being in contact with the front face of the panel,
• a layer of cellular material disposed between the first and the second layers of rigid material, the layer of cellular material being in contact with the first layer of rigid material and with the second layer of rigid material.
