Minimizing CT Angiography Radiation Burden While Maintaining Accuracy Through Noise Reduction

Novel X-ray image noise reduction technology reduces patient radiation dose while maintaining image quality in coronary angiography

AIMS The consequences of high radiation dose for patient and staff demand constant improvements in X-ray dose reduction technology. This study assessed non-inferiority of image quality and quantified patient dose reduction in interventional cardiology for an anatomy-specific optimised cine acquisition chain combined with advanced real-time image noise reduction algorithms referred to as 'study ...

Minimizing Hypoglycemia While Maintaining Glycemic Control in Diabetes

In an accompanying Perspectives article, Cryer (1) identifies a number of different areas where therapeutic interventions have the potential to reduce hypoglycemia without compromising glycemic control. Some approaches provide well-defined clinical benefits, a few offer dramatic reductions in hypoglycemia but remain out of reach for most people, and others, although promising, have yet to be pr...

Minimizing Dissemination in a Population While Maintaining its Community Structure

Given a population represented as a graph (e.g., a social network where the nodes are individuals and the links indicate friendships), can we minimize the spread of an entity (such as a meme or a virus) while maintaining the population’s community structure (i.e., dense connections among nodes within a community but sparse connections between nodes in different communities)? At first glance, th...

Shearlet-Based Adaptive Noise Reduction in CT Images

The noise in reconstructed slices of X-ray Computed Tomography (CT) is of unknown distribution, non-stationary, oriented and difficult to distinguish from main structural information. This requires the development of special post-processing methods based on the local statistical evaluation of the noise component. This paper presents an adaptive method of reducing noise in CT images employing th...
