Correction to “Thermal Molecular Motion Can Amplify Intermolecular Magnetic Interactions”

Action can amplify motion-induced illusory displacement

Local motion is known to produce strong illusory displacement in the perceived position of globally static objects. For example, if a dot-cloud or grating drifts to the left within a stationary aperture, the perceived position of the whole aperture will also be shifted to the left. Previously, we used a simple tracking task to demonstrate that active control over the global position of an objec...

Advanced Motion Correction Methods in PET

With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...

Perturbation analyses of intermolecular interactions.

Conformational fluctuations of a protein molecule are important to its function, and it is known that environmental molecules, such as water molecules, ions, and ligand molecules, significantly affect the function by changing the conformational fluctuations. However, it is difficult to systematically understand the role of environmental molecules because intermolecular interactions related to t...

Advanced Motion Correction and Image Reconstruction for Cardiac Magnetic Resonance

Correction of Motion Artefacts in Magnetic Resonance Imaging

Magnetic Resonance Imaging (MRI) can provide high quality images exhibiting good soft tissue contrast and without the use of potentially harmful ionising radiation. The process of MR image formation is inherently slow compared to many physiological processes and this can lead to image artefacts such as a blurring and ghosting. The aim of the project was to correct for motion artefacts. MR data ...
