An anti-scatter device for suppressing scattered radiation includes a plurality of x-ray absorbing layers. The anti-scatter device further includes a plurality of spacer layers, such that each spacer layer is arranged between any two of the plurality of x-ray absorbing layers in order to hold each of the x-ray absorbing layers in a pre-defined orientation. Furthermore, each of the spacer layers includes a plurality of unsealed voids to reduce the absorption of x-rays incident on at least a portion of each of the spacer layers.
