Anti-scattering x-ray raster |
摘要 |
An anti-scatter X-ray raster provides suppression of secondary scattered Compton radiation thus improving image contrast. The anti-scatter X-ray raster comprises a plurality of tubular channels made of an X-ray absorbing material. The tubular channels are spliced together to form a cellular structure. The largest cross size (d) of a singe channel its length (H) meet a relationship 2d/H>thetac, where thetac is a critical angle of total external reflection of X-rays from the material forming the walls of the tubular channels. The cross-section of the tubular channels need not be circular but may be, for example triangular or hexagonal. In a non-focused raster embodiment all of the longitudinal axis of the channels are parallel. In focused embodiments, the longitudinal axis of the channels are radially angled such that if extended they would meet at the X-ray source point.
