Compressed Sensing Based Computed Tomography Image Reconstruction
In computed tomography (CT), an important objective is to reduce radiation dose without degrading image quality. The radiation exposure from CT scan will make severe problem in humans. This has high risk in the case of children and female. The higher exposure will lead to leukemia, cancer etc. So that low dose CT image reconstruction is the main concern now days. We have to reconstruct the imag...
متن کاملSparse-Coding-Based Computed Tomography Image Reconstruction
Computed tomography (CT) is a popular type of medical imaging that generates images of the internal structure of an object based on projection scans of the object from several angles. There are numerous methods to reconstruct the original shape of the target object from scans, but they are still dependent on the number of angles and iterations. To overcome the drawbacks of iterative reconstruct...
متن کاملThree-dimensional reconstruction of New Zealand rabbit antebrachium by multidetector computed tomography
The aim of this study was to reveal biometric peculiarities of New Zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. Under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic MDCT. Biometric measurements of the reconstructed...
متن کاملReconstruction of High-Resolution Computed Tomography Image in Sinogram Space
An important part of any computed tomography (CT) system is the reconstruction method, which transforms the measured data into images. Reconstruction methods for CT can be either analytical or iterative. The analytical methods can be exact, by exact projector inversion, or non-exact based on Back projection (BP). The BP methods are attractive because of thier simplicity and low computational co...
متن کاملTotal variation superiorization schemes in proton computed tomography image reconstruction.
PURPOSE Iterative projection reconstruction algorithms are currently the preferred reconstruction method in proton computed tomography (pCT). However, due to inconsistencies in the measured data arising from proton energy straggling and multiple Coulomb scattering, the noise in the reconstructed image increases with successive iterations. In the current work, the authors investigated the use of...
