Phase contrast X-ray imaging
In the last decade X-ray imaging based on phase contrast greatly advanced thanks to the use of unmonochromatic synchrotron hard X-rays. The recent advances are going beyond microradiology and microtomography to reach nanometre scale. This paper reviews basic theory and selected applications to biomedical and materials sciences. The forthcoming improvements in phase contrast X-ray imaging will ...

Mammography image quality optimisation: a Monte Carlo study
Different irradiation configurations for typical mammographic facilities were evaluated in order to establish optimal irradiation parameters for improving X-ray image quality. The whole X-ray imaging process was suitably studied by means of Monte Carlo techniques. Relevant parameters were introduced to the program in order to evaluate their effect on image quality. Breast absorbed doses were ...

I)Video Management (VM) for operating theatres: Is there a standard need?
Part 1: Identify the real need Today hospitals, and in particular operating theaters, have become hubs of innovation. There is a real proliferation of solutions, functions and various technologies, with manufacturers, resellers or suppliers offering tailor-made and sometimes scalable solutions. These solutions are often captive and proprietary and do not always allow you to compose your own ...

Predicting the impact of keeping a distance at security divestment
As travel restrictions are slowly eased and airlines start to offer more regular connections, airports are looking for ways how to implement improved hygiene standards and social distancing guidance throughout the passenger journey without compromising security, efficiency or profitability. Achieving this is likely to be a key factor in gaining a competitive advantage in the recovery phase. ...

A New Device to Markedly Reduce Cardiac Cath Lab Radiation Levels
Background: Exposure of the heart team to scatter radiation is a serious environmental risk in the cardiac cath lab. While spot shielding reduces operator exposure, its effectiveness in reducing overall room scatter radiation (SR) levels, particularly during imaging with angulated x-ray views, is limited. We evaluated the effectiveness of a new, passive protection system (the EggNest) to reduce ...

Triiodophenyl acrylate–based microbeads find important use in the medical field
Preparation of polymeric micro– and nanoparticles has significantly become an effective approach for achieving efficient drug targeting to tumour tissues. A promising solution could be the use of a radio–opaque polymeric system carrying iodine groups. In this context, radio–opaque polymeric microparticles based on methyl methacrylate (MMA) and an 2,4,6–triiodophenyl acrylate (TIPA) were ...

Understanding Pediatric Cardiomyopathy: Causes, Symptoms and Treatment Options
Up to 5,000 American infants and children are diagnosed with pediatric cardiomyopathy each year. Learn more about this rare but potentially serious condition. Cardiomyopathy, which is a general term for diseases of the heart muscle, is relatively rare in children, affecting only about 12 out of every 1 million Americans under the age of 18. Among the approximately 1,000 to 5,000 new cases ...
