Conventional coronary angiography is currently the gold standard in the detection and
diagnosis of coronary artery disease. This modality, however, is invasive in nature. Hence …

This paper discusses image reconstruction with a tilted gantry in multislice computed
tomography (CT) with helical (spiral) data acquisition. The reconstruction problem with …

A new approximate method for the utilization of redundant data in helical cone‐beam CT is
presented. It is based on the observation that the original WEDGE method provides …

X-ray computed tomography is a widely adopted medical imaging method that uses
projections to recover the internal image of a subject. Since the invention of X-ray computed …

Recently one of the authors proposed a reconstruction algorithm, which is theoretically exact
and has the truly shift-invariant filtering and backprojection structure. Each voxel is …

We present a novel reconstruction algorithm for high-transaxial-resolution cone-beam
computed tomography (CT). Two ideas are combined to achieve this: First, the ray-offset …

Modern CT systems have advanced at a dramatic rate. Algebraic iterative reconstruction
techniques have shown promising and desirable image characteristics, but are seldom used …

The invention relates to a computed tomography method in which an examination Zone is
irradiated along a helical tra jectory by a conical radiation beam. The radiation transmitted …

Katsevich proposed a reconstruction algorithm for helical cone-beam CT which is
theoretically exact. Even for large cone angles, it performs very well on static objects. But …

Modern CT scanners use energy-integrating detectors, but most existing reconstruction
algorithms are based on photon counting detector models. We implemented an expectation …
