Fig. 1

A 2-D illustration of Radon transform geometry. On the right: Radon transform of a pixel (tensor-product first-order B-spline) leads to a 1-D box spline whose directions are the geometric projection of the directions of the source box spline. This property directly generalizes to 3-D for voxel or higher-order basis.
