CT imaging is widely used in medical science over the last decades. The process of CT
image reconstruction depends on many physical measurements such as radiation dose …

Owing to recent advances in computing power, iterative reconstruction (IR) algorithms have
become a clinically viable option in computed tomographic (CT) imaging. Substantial …

The avascular nature of cartilage makes it a unique tissue,,–, but whether and how the
absence of nutrient supply regulates chondrogenesis remain unknown. Here we show that …

Although diagnostic medical imaging provides enormous benefits in the early detection and
accuracy diagnosis of various diseases, there are growing concerns on the potential side …

Multislice helical computed tomography scanning offers the advantages of faster acquisition
and wide organ coverage for routine clinical diagnostic purposes. However, image …

Low-dose computed tomography (LDCT) images are often severely degraded by amplified
mottle noise and streak artifacts. These artifacts are often hard to suppress without …

High-end CT systems allow acquisition of isotropic volumetric data sets that permit high
quality reformatted images and images with less than 1 mm slice thickness. These …

This paper describes a statistical image reconstruction method for X-ray computed
tomography (CT) that is based on a physical model that accounts for the polyenergetic X-ray …

Despite universal consensus that computed tomography (CT) overwhelmingly benefits
patients when used for appropriate indications, concerns have been raised regarding the …

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