Spatial resolution object and CT imaging. (a) The CAD model of the spatial object, where copper plates were inlaid in a plastic cylinder. (b) Cross section image of the object. The resolution structures varied over 0.3–10LP/mm. (c) A projection image of the spatial object after two collimators. The object was placed on an aluminum holder, connected to the rotation stage. (d) A sinogram image of a slice of the object generated from 400 projection images at 0.5° intervals. (e) The reconstructed tomography image from (d) using a filtered back projection (FBP) algorithm.
