A New Method for Metal Artifact Reduction in CT Scan Images
Introduction In CT imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. In order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. Materials and Methods The presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...
متن کاملMetal artifact reduction in CT using fusion based prior image.
PURPOSE In computed tomography, metallic objects in the scanning field create the so-called metal artifacts in the reconstructed images. Interpolation-based methods for metal artifact reduction (MAR) replace the metal-corrupted projection data with surrogate data obtained from interpolation using the surrounding uncorrupted sinogram information. Prior-based MAR methods further improve interpola...
متن کاملCT Image Reconstruction by Spatial-Radon Domain Data-Driven Tight Frame Regularization
This paper proposes a spatial-Radon domain CT image reconstruction model based on data-driven tight frames (SRD-DDTF). The proposed SRD-DDTF model combines the idea of joint image and Radon domain inpainting model of [1] and that of the data-driven tight frames for image denoising [2]. It is different from existing models in that both CT image and its corresponding high quality projection image...
متن کاملArtifact reduction in dual-energy CT reconstruction for security applications
In this paper we present a structure-preserving dual-energy (SPDE) CT reconstruction method for security, which provides enhanced estimates of material-dependent basis coefficient images. In security applications many different materials may be scanned in various degrees of clutter and metal objects are common. Image noise and metal artifacts are often severe and can lower the accuracy of mater...
متن کاملSinogram constrained TV-minimization for metal artifact reduction in CT
A new method for reducing metal artifacts in X-ray computed tomography (CT) images is presented. It bases on the solution of a convex optimization problem with inequality constraints on the sinogram, and total variation regularization for the reconstructed image. The Chambolle-Pock algorithm is used to numerically solve the discretized version of the optimization problem. As proof of concept we...
