Projection and backprojection are operations that arise frequently in tomographic imaging.
Recently, we proposed a new method for projection and backprojection, which we call …

Low-dose computed tomography (LDCT) scans, which can effectively alleviate the radiation
problem, will degrade the imaging quality. In this paper, we propose a novel LDCT …

Statistical image reconstruction using penalized weighted least-squares (PWLS) criteria can
improve image-quality in X-ray computed tomography (CT). However, the huge dynamic …

Sparse-view computed tomography (CT) is one of the primary means to reduce the radiation

Sparse-view computed tomography (CT) is one of the primal means to reduce radiation risk.
However, the reconstruction of sparse-view CT with the classic analytical method is usually …

The ray-driven projection and back-projection methods, frequently represented as
calculating the path of line integration through a pixel or voxel space, are widely applied in …

An X-ray cargo inspection system with few-view projection imaging is developed for
detecting contraband in air containers. This paper describes this developing inspection …

It is well known that l 1 minimization can be used to recover sufficiently sparse unknown
signals in the compressive sensing field. The lp regularization method, a generalized …

Projection and backprojection operations are essential in a variety of image reconstruction
and physical correction algorithms in computed tomography (CT). The distance-driven (DD) …
