Title:
ANTI-SCATTER GRID FOR RADIATION DETECTOR
Document Type and Number:
WIPO Patent Application WO/2017/070961
Kind Code:
A1
Abstract:
An anti-scatter grid (820), a detector (1100) with such an anti-scatter grid (820) and a radiation imaging system including such a detector (1100) with an anti-scatter grid (820) are provided. The anti-scatter grid (820) includes at least one grid wall (G). The parameters of the grid wall (G) may be adjusted to arrive at a uniform scatter-to-primary ratio. The parameters of the grid wall (G) comprise thickness, height, shape, or position of the grid wall (G), or width of the interspace between two grid walls (G). The detector (1100) includes the anti-scatter grid (820), at least one photosensor (720), and at least one scintillator (810). The radiation system includes a radiation generator, a radiation detector (1100) with the anti-scatter grid (820), and a processor.
