Abstract:
An x-ray detector comprising:an x-ray opaque outer housing;a plurality of detector elements housed in said x-ray opaque outer housing, each of said detector elements comprising a scintillator element, an optical coupling element and a photo-detector element; andattachment means for mounting and aligning said plurality of detector elements, said attachment means comprising means for x-positioning, means for y-positioning and means for rotational positioning;wherein said scintillator elements are attached to an adjuster plate;wherein said means for x-positioning comprises an x-axis positioning screw attached to the side of said outer housing and a first spring loaded return pin located on the side of said outer housing diametrically opposite said x-axis positioning screw, said first return pin biasing said adjuster plate against said x-axis positioning screw;wherein said means for y-positioning comprises a y-axis positioning screw attached to the side of said outer housing substantially perpendicular to said x-axis positioning screw and a second spring loaded return pin located on the side of said outer housing diametrically opposite said y-axis positioning screw, said second return pin biasing said adjuster plate against said y-axis positioning screw; andwherein said means for rotational positioning comprises a rotational bracket, having two end plates, supporting a rotational positioning screw on said one end plate and a third spring loaded return pin on said other end plate, and a tongue integrally attached to said outer housing, said tongue placed between said two end plates and biased by said third return pin against said rotational positioning screw.
