WebMar 15, 2024 · Binary tomography aims to reconstruct binary images from their projections. Possible applications can be the field of human X-ray angiography, where … WebBinary tomography is concerned with the recovery of binary images from a few of their projections (i.e., sums of the pixel values along various directions). To reconstruct an image from noisy projection data, one can pose it as a constrained least-squares problem. As the constraints are nonconvex, many approaches for solving it rely on either ...

WebMay 18, 2024 · Binary tomography reconstructs binary images from a low number of their projections. Often, there is a freedom how these projections can be chosen which can significantly affect the quality of reconstructions. We apply sequential feature selection methods to find the ‘most informative’ projection set based on a blueprint image. WebFeb 1, 2024 · In this paper, the binary tomographic reconstruction problem for very limited projection data availability is considered. Being this inverse problem highly ill-posed, we propose a new ...
WebFeb 1, 2012 · Binary tomography (BT) represents a special type of tomography problem, in which the sought function can only assume two possible discrete values (e.g., 0 and 1) [1]. Due to this binary nature, the BT problem usually requires projections from only a few view angles to solve, in stark contrast to the hundreds or thousands of view angles … WebOct 14, 2024 · Computed Tomography-Based Radiomics in Predicting T Stage and Length of Esophageal Squamous Cell Carcinoma. ... Third, OS and PFS were treated as binary variables, and survival prediction was based only on patients’ survival status. Therefore, in future research, the predictive ability of survival span will also be examined. ...
