摘要: A radiation detector (30) for a computed tomography scanner (12) includes support structure (62). An alignment board (60) secures to the (62) and photolithographically defined openings (70) arranged define spatial focal point (34) relative (60). anti scatter element (32) is disposed on one or more protrusions (86) which mate with of align (34). (104) structures (106) that (32).
