TI  - Efficient volume reconstruction for parallel-beam computed laminography by 
      filtered backprojection on multi-core clusters.
PG  - 5348-61
AB  - Computed laminography (CL) was developed to use X-rays from synchrotron sources 
      for high-resolution imaging of the internal structure of a flat specimen from a 
      series of 2-D projection images. The projections are acquired by irradiation of 
      the sample under different rotation angles where the object rotation axis is 
      inclined with respect to the beam direction. This yields for laterally extended 
      objects a more uniform average transmitted intensity during sample rotation 
      compared with computed tomography (CT). The reconstruction problem of CL cannot 
      be reduced to a data-efficient 2-D case (as for parallel-beam CT) since each 
      single slice perpendicular to the rotation axis requires a 2-D region on the 
      detector as input data for all projection directions. This paper describes a 
      computationally efficient reconstruction procedure based on filtered 
      backprojection (FBP) adapted to the CL acquisition geometry. From the Fourier 
      slice theorem, we derive a framework for analytic image reconstruction and 
      outline implementation details of the generic FBP algorithm. Different approaches 
      reducing the reconstruction time by means of parallel and distributed 
      computations are considered and evaluated.
