Low-dose Computed Tomography (CT) becomes an increasingly significant research object
in recent years result from the harm of radiation used in X-ray CT to health of patients …

Low dose computed tomography (LDCT) can reduce the radiation hazard to patients
effectively. However, mottle noise and streak artifacts often lower and degenerate the quality …

Improving image quality is a critical objective in low dose computed tomography (CT)
imaging and is the primary focus of CT image denoising. State‐of‐the‐art CT denoising …

The clinical demand for low image noise often limits the slice thickness used in many CT
applications. However, a thick-slice image is more susceptible to longitudinal partial volume …

Computed tomography (CT) delivers a dose of radiation to the patient, presenting an
important risk. However, reducing the radiation dose can introduce noise into CT images. To …

Low-dose computed tomography (LDCT) images are polluted by mottle noise and streak
artifacts. To improve LDCT images quality, this paper proposes a novel total variation (NTV) …

Purpose: Because of high diagnostic accuracy and fast scan time, computed tomography
(CT) has been widely used in various clinical applications. Since the CT scan introduces …

The purpose of this paper is to improve the quality of low dose Computed Tomography (CT)
images. Low dose artifacts are the Gaussian noises superimposed on the CT images and …

Low-dose computed tomography (LDCT) is an effective approach to reduce radiation
exposure to patients. Lots of mottle noise and streak artifacts, however, are introduced to the …

X-ray computed tomography (CT) is now a widely used imaging modality for numerous
medical purposes. The risk of high X-ray radiation may induce genetic, cancerous and other …
