X-ray detection device

An X-ray detection device comprising:

• a housing;
• an X-ray detector located in the housing and configured to detect X-rays within an energy detection range of the X-ray detector;
• a collimator opaque in at least part of the energy detection range and partially covering the X-ray detector;
• and
• a first shielding element opaque in at least part of the energy detection range, wherein the first shielding element is configured to provide at least one of:
• a protection of the X-ray detector against stray X-rays within the energy detection range coming from the housing and/or from the collimator, or
• a protection of the housing and/or the collimator from at least one of the stray X-rays or other X-rays,
• wherein the housing comprises a cap and at least one of a socket, a circuit board, a spacer or a cooling unit, the X-ray detector being mounted on the at least one of the socket, the circuit board, the spacer or the cooling unit,
• wherein the cap comprises an opening and a window closing the opening so that an enclosed space is encased by the cap together with at least one of the socket, the spacer, the cooling unit or the circuit board,
• wherein the X-ray detector is located in the enclosed space,
• wherein the first shielding element is located between the X-ray detector and the at least one of the socket, the circuit board, the spacer or the cooling unit,
• wherein the first shielding element has a centrally located shielding element opening and the at least one of the socket, the spacer, the cooling unit or the circuit board has a board opening,
• wherein the board opening and the shielding element opening overlap at least partially, and
• wherein the shielding element opening has the same diameter as the board opening, seen in top view of the X-ray detector.
