Software for Time Interlaced Model Based Iterative Reconstruction (TIMBIR)
Summary The time-interlaced model-based iterative reconstruction (TIMBIR) [1,2] is a method for 4D time-space reconstruction of data acquired using synchrotron X-ray computed tomography. TIMBIR is a synergistic combination of two innovations. The first innovation, interlaced view sampling, is a novel method of data acquisition which distributes the view angles more evenly in time. The second …

3D Model-Based Iterative Reconstruction for Synchrotron Tomography
Introduction and Theory Synchrotron based X-ray tomography is widely used for three dimensional imaging of material samples. Typically, reconstructions are done using analytical reconstruction techniques such as filtered back projection (FBP) or Fourier reconstruction methods like gridrec. However, direct reconstruction of synchrotron data typically result in strong ring and streak artifacts in the reconstruction. The …
