Efficient implementation of a local tomography reconstruction algorithm
We propose an efficient implementation of an interior tomography reconstruction method based on a known subregion. This method iteratively refines a reconstruction, aiming at reducing the local tomography artifacts. To cope with the ever increasing data volumes, this method is highly optimized on two aspects: firstly, the problem is reformulated to reduce the number of variables, and secondly, ...
متن کاملA practical local tomography reconstruction algorithm based on known subregion
A new method to reconstruct data acquired in a local tomography setup is proposed. This method uses an initial reconstruction and refines it by correcting the low-frequency artifacts, known as the cupping effect. A basis of Gaussian functions is used to correct the initial reconstruction. The coefficients of this basis are found by optimizing iteratively a fidelity term under the constraint of ...
متن کاملEfficient parallel implementation of iterative reconstruction algorithms for electron tomography
Electron tomography (ET) combines electron microscopy and the principles of tomographic imaging in order to reconstruct the threedimensional structure of complex biological specimens at molecular resolution. Weighted back-projection (WBP) has long been the method of choice since the reconstructions are very fast. It is well known that iterative methods produce better images, but at a very costl...
متن کاملRadon Transform based Local Tomography Algorithm for 3 D Reconstruction
An algorithm from Radon transform to obtain local tomography from multiple CT slices for localized 3D reconstruction is developed. The proposed method uses Radon transform to obtain projections for a region of interest. Reconstructing a particular cross section of a human body using local data will significantly reduce Xray exposure during imaging. Image reconstruction is performed using filter...
متن کاملAnalysis of Local Community Perception of Physical-Spatial Reconstruction of Hadi Project Implementation in Roshtkhar District
Introduction Many rural development projects and projects are not being evaluated. Therefore, rural developers rarely know their short-term and long-term implications. On the other hand, in order to achieve efficient service and comprehensive coverage of services in all rural areas, emphasis is placed on reaching the hierarchy of rural areas, and to achieve these two objectives, the preparatio...
