Iterative Reconstruction of SPECT Images Using Adaptive Multi-level Refinement
We present a novel method for iterative reconstruction of high resolution images. Our method is based on the observation that constant regions in an image can be represented at much lower resolution than region with fine details. Therefore, we combine adaptive refinement based on quadtrees with iterative reconstruction to reduce the computational costs. In our experiments we found a speed up fa...
متن کاملBuilding Reconstruction from Lidar Data Using Iterative Regularization Approach
This paper presents a scheme for the reconstruction of building models from LIDAR data by using an iterative regularization approach. The proposed scheme comprises three major parts: (1) elevation slicing, (2) boundary regularization, and (3) roof determination. The idea of elevation slicing is similar to the elevation contour map, where each contour line indicates a height level. We select a h...
متن کاملIterative CT Reconstruction Using Curvelet-Based Regularization
There is a critical need to reconstruct clinically usable images at a low dose. One way of achieving this is to reconstruct with as few projections as possible. Due to the undersampling, streak artifacts degrade image quality for traditional CT reconstruction. Compressed sensing (CS) [1] theory uses sparsity as a prior and improves the reconstruction quality considerably using only few projecti...
متن کاملConvergent Iterative CT Reconstruction With Sparsity-Based Regularization
Statistical image reconstruction for X-ray CT can provide improved image quality at reduced patient doses. An important component of statistical reconstruction methods is the regularizer. There has been increased interest in sparsity-based regularization, typically using l1 norms. The non-smooth nature of these regularizers is a challenge for iterative optimization methods and often causes slow...
متن کاملCT of the chest with model-based, fully iterative reconstruction: comparison with adaptive statistical iterative reconstruction
BACKGROUND The recently developed model-based iterative reconstruction (MBIR) enables significant reduction of image noise and artifacts, compared with adaptive statistical iterative reconstruction (ASIR) and filtered back projection (FBP). The purpose of this study was to evaluate lesion detectability of low-dose chest computed tomography (CT) with MBIR in comparison with ASIR and FBP. METHO...
