LOR-OSEM: Statistical PET Reconstruction from Raw LOR Histograms
Iterative statistical reconstruction methods are becoming the standard in positron emission tomography (PET). Conventional maximum-likelihood expectation-maximization (MLEM) and ordered-subsets (OSEM) algorithms act on data which has been pre-processed into corrected, evenly-spaced histograms; however, such pre-processing corrupts the Poisson statistics. Recent advances have incorporated attenu...
متن کاملCorrection for external LOR effects in listmode reconstruction for PET
In PET imaging listmode is an alternative for projections to store the acquisition data with more accuracy. The reconstruction starting from the listmode format requires different approaches than projection based algorithms. The ML-EM algorithm was modified to start from the listmode format. For listmode data mage degrading effects can be classified into two groups. Internal LOR effects (like a...
متن کاملUltra fast, accurate PET image reconstruction for the Siemens hybrid MR/BrainPET scanner using raw LOR data
Forschungszentrum Jülich GmbH, Jülich, Germany Fast PET image reconstruction algorithms usually use a Line-of-Response (LOR) preprocessing step where the detected raw LOR data are interpolated either to evenly spaced sinogram projection bins or alternatively to a generic projection space as for example proposed by the PET Reconstruction Software Toolkit (PRESTO) [1]. In this way, speed-optimise...
متن کاملAnalysis of MLEM and OSEM Reconstruction Algorithms for Different Geometries of PET Scanners
At the experimental heavy ion tumor therapy facility at the GSI Darmstadt in-beam PET is operated. The in-beam PET data should be reconstructed as fast as possible (ideally, in real time), because they allow monitoring irregularities in beam delivery. To find a fast reconstruction algorithm with acceptable quality, MLEM [1] and OSEM [2] algorithms were compared for full-ring and dual-head geome...
متن کاملSimulation-based evaluation of OSEM iterative reconstruction methods in dynamic brain PET studies
The reconstruction of dynamic PET data is usually performed using filtered backprojection algorithms (FBP). This method is fast, robust, linear and yields reliable quantitative results. However, the use of FBP for low count data, such as dynamic PET data, generally results in poor visual image quality, exhibiting high noise, disturbing streak artifacts and low contrast. These signal-to-noise ra...
