  • Scintillator pack comprising an X-ray absorbing encapsulation and X-ray detector array comprising such scintillator pack
    Patent number: 9599728
    Abstract: A scintillator pack (2) and a CT X-ray detector array (1) comprising such scintillator pack (2) are proposed. The scintillator pack (2) comprises an array of scintillator pixels (3). At a bottom surface (31) of each scintillator pixel (3), an X-ray absorbing encapsulation (13) is provided. This encapsulation (13) comprises an electrically insulating highly X-ray absorbing material having an atomic number greater than 60 such as, for example, Bismuth oxide (Bi2O3). The X-ray absorbing encapsulation (13) is interposed between the scintillator pixels (3) and an electronic circuit (19). The electronic circuit (19) may be provided as an ASIC in CMOS technology and may therefore be sensitive to X-ray induced damage. The encapsulation (13) provides for good X-ray protection of such electronic circuit (19).
