ANTI-SCATTER GRID

摘要

An anti-scatter apparatus (118) of an imaging system (100) including a base (204) with a plurality of detector tile receiving sub-regions (208) consecutively abutted and aligned along a z-axis direction of the imaging system (100). A tile receiving sub-region (208) is configured to receive a individual detector tile (210), which includes a matrix of photosensing pixels. The tile receiving sub-region (208) includes a plurality of channels (306), which are respectively aligned with different ones of the photosensing pixels. A bracket (402) is affixed to the base (204) so that detector tiles (210) installed in the plurality of tile receiving sub-regions (208) are disposed between the bracket (402) and the plurality of tile receiving sub-regions (208), thereby securing the installed detector tiles (210) in the anti-scatter apparatus (118). A fastening portion (206, 1102) fastens to a detector module cradle (120) of the imaging system (100), thereby securing the anti-scatter apparatus (118) to the imaging system. The fastening portion (206, 1102) is fastened to the detector module cradle (120) to focus the channels at a focal spot of a radiation source (110) of the imaging system (100).
