3D spatial resolution characterization for volumetric computed tomography
نویسندگان
چکیده
Spatial resolution is a key parameter that determines the smallest resolved scale in volumetric computed tomography. However, evaluation process typically confined within plane, and tomographic usually treated as two dimensional concept. In this work, full map of three-dimensional (3D) spatial along radial directions was obtained through combined laser induced fluorescence measurement on well-controlled test rig, reconstruction, successive analysis. The results show non-uniformly distributed weak dependence view angles. Moreover, both experimental algorithmic factors were quantitatively quantified. convergence then validated series computation with increasing voxel numbers. It found improves until number voxels reaches ∼19.6 times much value set by linear algebraic limit. ultimate can be our setup about 1.35 lp/mm, which twice well-posed system. method work more appropriate to quantify 3D space. conclusions made generalized for applications other tomography-based measurements.

Enhanced Spatial Resolution Using Iterative Focal Desmearing in Computed Tomography
Computed tomography reconstructions of projected data usually assume an ideal point-like focal spot. However, in practice, the actual finite focus size leads to blurred projections, unavoidably. The elements (voxels) of the reconstruction array are smeared differently as a function of their individual position relative to source and detector. Neglecting the focal smearing generates considerably...
متن کاملHigh-resolution computed tomography
This paper investigates high-resolution reconstructions from eeciently sampled data in parallel-beam tomography, in particular local tomography. A class of sampling schemes is deened and characterized, and it is shown that the standard scheme and the interlaced scheme of Cormack are most promising. An error analysis for the ltered backprojection algorithm for both global and local tomography is...
