Patent ID: 8884235

Claim:
A method for manufacturing a collimator of an imaging system, the method comprising: coupling tubes together to form a stack of parallel hole collimator segments or forming a corrugated collimator core; cutting the stack or the corrugated collimator core at one or more pointing directions to form a plurality of slanted collimator segments in a linear arrangement S 1 -S 5 wherein at least one of the slanted collimator segments has bores cut perpendicular to a face of the stack or the corrugated collimator core to form an untilted segment S 3 ; and coupling the plurality of slanted collimator segments together to form a segmented type collimator, wherein the untilted collimator segment S 3 is positioned central to the collimator, and at least two pairs of the slanted collimator segments S 2 ,S 4 and S 1 ,S 5 have collimator bores with different pointing directions and pointed inwardly to the same degree so as to arrange a fanbeam collimation configuration throughout the length of the collimator.
