Comparing IDREAM as an Iterative Reconstruction Algorithm against In Filtered Back Projection in Computed Tomography
Introduction: Recent studies of Computed Tomography (CT) conducted on patient dose reduction have recommended using an iterative reconstruction algorithm and mA (mili-Ampere) dose modulation. The current study aimed to evaluate Iterative Dose Reduction Algorithm (IDREAM) as an iterative reconstruction algorithm. Material and Methods: Two CT p...
متن کاملFiltered back projection, adaptive statistical iterative reconstruction, and a model-based iterative reconstruction in abdominal CT: an experimental clinical study.
PURPOSE To compare objective and subjective image quality parameters of three image reconstruction algorithms of different generations at routine multidetector computed tomographic (CT) examinations of the abdomen. MATERIALS AND METHODS This institutional review board-approved study included 22 consecutive patients (mean age, 56.1 years ± 15.8 [standard deviation]; mean weight, 79.1 kg ± 14.8...
متن کاملEnhanced Spatial Resolution in 2D CT-Reconstruction without Filtered Back-Projection: DIRECTT
We report on novel developments of the DIRECTT (Direct Iterative Reconstruction of Computed Tomography Trajectories) algorithm. Details are discussed for model calculations in order to elucidate its universal character for parallel and fan beam geometry. Our approach represents a promising alternative to the conventional filtered back-projection (FP). Instead of Fourier transforming single proj...
متن کاملGeneralized Filtered Back-projection for Digital Breast Tomosynthesis Reconstruction
Filtered back-projection (FBP) has been commonly used as an efficient and robust reconstruction technique in tomographic X-ray imaging during the last decades. For limited angle tomography acquisitions such as digital breast tomosynthesis, however, standard FBP reconstruction algorithms provide poor results and give rise to image artifacts due to the limited angular range and the coarse angular...
متن کاملImpact of iterative reconstruction vs. filtered back projection on image quality in 320-slice CT coronary angiography
Iterative reconstruction has been shown to reduce image noise compared with traditional filtered back projection with quantum denoising software (FBP/QDS+) in CT imaging but few comparisons have been made in the same patients without the influence of interindividual factors. The objective of this study was to investigate the impact of adaptive iterative dose reduction in 3-dimensional (AIDR 3D)...
