A review on CT image noise and its denoising
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 …

Low-dose CT via convolutional neural network
H Chen, Y Zhang, W Zhang, P Liao, K Li… - Biomedical optics …, 2017 - opg.optica.org
In order to reduce the potential radiation risk, low-dose CT has attracted an increasing
attention. However, simply lowering the radiation dose will significantly degrade the image …

Radiation dose reduction in computed tomography: techniques and future perspective
Despite universal consensus that computed tomography (CT) overwhelmingly benefits
patients when used for appropriate indications, concerns have been raised regarding the …

Artifact suppressed dictionary learning for low-dose CT image processing
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 …

Adaptive-weighted total variation minimization for sparse data toward low-dose x-ray computed tomography image reconstruction
Previous studies have shown that by minimizing the total variation (TV) of the to-be-
estimated image with some data and other constraints, piecewise-smooth x-ray computed …
