Iterative image reconstruction for CBCT using edge-preserving prior.
On-board cone-beam computed tomography (CBCT) is a new imaging technique for radiation therapy guidance, which provides volumetric information of a patient at treatment position. CBCT improves the setup accuracy and may be used for dose reconstruction. However, there is great concern that the repeated use of CBCT during a treatment course delivers too much of an extra dose to the patient. To re...
متن کاملIterative Image Reconstruction for Sparse-View CT Using Normal-Dose Image Induced Total Variation Prior
X-ray computed tomography (CT) iterative image reconstruction from sparse-view projection data has been an important research topic for radiation reduction in clinic. In this paper, to relieve the requirement of misalignment reduction operation of the prior image constrained compressed sensing (PICCS) approach introduced by Chen et al, we present an iterative image reconstruction approach for s...
متن کاملIterative image reconstruction using prior knowledge.
A method is proposed to reconstruct signals from incomplete data. The method, which can be interpreted both as a discrete implementation of the so-called prior discrete Fourier transform (PDFT) spectral estimation technique and as a variant of the algebraic reconstruction technique, allows one to incorporate prior information about the reconstructed signal to improve the resolution of the signa...
متن کاملContrast-Induced Nephropathy Following CT Scan and Its Associated Factors
Background and purpose: Contrast-induced nephropathy (CIN) as a common complication of administration of contrast media (CM) is a major source of hospital morbidity and mortality. The aim of this study was to determine the incidence of CIN after contrast-enhanced CT scan and identifying the related risk factors. Materials and methods: A cross-sectional study was carried out in 100 patients att...
متن کاملTechniques in Iterative Proton CT Image Reconstruction
This is a review paper on some of the physics, modeling, and iterative algorithms in proton computed tomography (pCT) image reconstruction. The primary challenge in pCT image reconstruction lies in the degraded spatial resolution resulting from multiple Coulomb scattering within the imaged object. Analytical models such as the most likely path (MLP) have been proposed to predict the scattered t...
