The ability of biomedical imaging data to be of quantitative nature is getting increasingly
important with the ongoing developments in data science. In contrast to conventional …

Grating-based X-ray interferometry offers vast potential for imaging materials and tissues
that are not easily visualised using conventional X-ray imaging. Tomographic reconstruction …

Purpose: The purpose of this work is to propose a cost function with regularization to
iteratively reconstruct attenuation, phase, and scatter images simultaneously from differential …

Purpose: The development of iterative image reconstruction algorithms for cone‐beam
computed tomography (CBCT) remains an active and important research area. Even with …

Differential phase-contrast is a recent technique in the context of X-ray imaging. In order to
reduce the specimen's exposure time, we propose a new iterative algorithm that can achieve …

The development of spectral computed tomography (CT) using binned photon-counting
detectors has garnered great interest in recent years and has enabled selective imaging of K …

Kaiser-Bessel window functions are frequently used to discretize tomographic problems
because they have two desirable properties: 1) their short support leads to a low …

We present a fast algorithm for fully 3D regularized X-ray tomography reconstruction for both
traditional and differential phase contrast measurements. In many applications, it is critical to …

Purpose Forward and backprojections are the basis of all model‐based iterative
reconstruction (MBIR) methods. However, computing these accurately is time‐consuming. In …

Optoacoustic tomography (OAT), also known as photoacoustic tomography, is an emerging
computed biomedical imaging modality that exploits optical contrast and ultrasonic detection …
