Magnetic resonance imaging (MRI) of the heart and lungs is a valuable diagnostic tool in the medical industry, but the detailed images it produces are often marred by artefacts (unwanted signals) created by the motion of cardiac and respiratory cycles.
A team of inventors at Oxford University has now developed a method of suppressing MRI artefacts to a negligible level. This has potential to allow more precise conclusions to be made from a small number of experimental trials, with obvious potential within the pharmaceutical industry, both to accelerate research work and to improve the robustness and quality of screening data upon which key project decisions can be made.
Cardiac and thoracic MRI of small animals, such as mice, requires high spatial resolution in order to resolve fine detail. However, MRI is extremely sensitive to motion from the cardiac and respiratory cycles, which cause severe image artefacts. To reduce these artefacts, synchronisation (gating) to these physiological cycles is required.

In a joint experimental and theoretical work performed at the Heidelberg Max Planck Institute for Nuclear Physics, an international team of physicists detected for the first time an orbital crossing in the highly charged ion Pr⁹⁺. Optical spectra were recorded employing an electron beam ion trap and analysed with the aid of atomic structure calculations. A proposed nHz-wide transition has been identified and its energy was determined with high precision. Theory predicts a very high sensitivity to new physics and extremely low susceptibility to external perturbations for this “clock line” making it a unique candidate for proposed precision studies.
Laser spectroscopy of neutral atoms and singly charged ions has reached astonishing precision by merit of a chain of technological advances during the past...
The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience gradually merged together and the first ultrafast microscopy of individual quantum dots (QDs) and molecules was accomplished.
Ultrafast microscopy studies entirely rely on detecting nanoparticles or single molecules with luminescence techniques, which require efficient emitters to...
Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronic applications. The results have just been published in the renowned journal Nature Nanotechnology.
Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties – for example,...
