摘要：

We prove the geometry of the essential support of rite Fourier transform of the X-ray transform when the detector trajectory is a circle, under the assumption that the measured function is essentially band-limited. Interlaced hexagonal sampling schemes are shown to be 4/root 3 more efficient than standard 3D orthogonal grids.
