Multienergy Element-Resolved Cone Beam CT (MEER-CBCT) Realized on a Conventional CBCT Platform
Purpose: Cone beam CT (CBCT) has been widely used in radiation therapy. However, its main application is still to acquire anatomical information for patient positioning. This study proposes a multienergy element-resolved ... -
Multienergy Cone-Beam Computed Tomography Reconstruction with a Spatial Spectral Nonlocal Means Algorithm
Multienergy computed tomography (CT) is an emerging medical image modality with a number of potential applications in diagnosis and therapy. However, high system cost and technical barriers obstruct its step into routine ... -
A Weighted Difference of Anisotropic and Isotropic Total Variation Model for Image Processing
(Society for Industrial and Applied Mathematics Publications, 2015-09-10)We propose a weighted difference of anisotropic and isotropic total variation (TV) as a regularization for image processing tasks, based on the well-known TV model and natural image statistics. Due to the form of our model, ...
