YNiC seminar TODAY
by rem 15 Oct '09

15 Oct '09

Today 4-5 pm in YNiC open plan. Jing Kan from the Department of Computer Science will talk about "Basis functions source model applied to MEG Spatio-Temporal Source Reconstruction". Everyone is welcome to attend. Best wishes Rebecca Abstract: The aim of this paper is to explore a new method of MEG source spatio-temporal reconstruction based on modeling the neural source with extended spherical basis functions. The high resolution 3D cortical mesh is extracted along with the corresponding MRI scan. Inspired by the theory that Laplacian eigenvectors of spherical mesh are equivalent to its basis functions which represent the whole mesh, we build a new model that describes the source distributed on each mesh vertex. This model consists of analogous basis functions and unknown weighted coefficients. Along with the leadfield, the weighted coefficients can be calculated in the light of forward formula of MEG.. The distributed neural source on the mesh is then reconstructed according to the above Basis functions expanded model. Expanding this process from single time point to continuous time series, it is possible to obtain the spatio-temporal reconstructed neural source distributed on cortical mesh vertices. Finally, the method is implemented using real data for signal reconstruction experiments. The robustness of this MEG reconstruction solution is discussed by two aspects. One is to compare with classical methods, i.e. minimum-norm method. The other is to apply the algorithm into meshes with different resolutions. It is clear that these approaches provide a new angle and inspiration of computer graphics to MEG signal reconstruction. Key word: MEG,, inverse problem, eigen-decomposition, basis function, Laplacian eigenvector, spheroidal model, weighted coefficient, spatio-temporal source reconstruction

[Fwd: TODAY: Where's the Physics in Medicine?]
by Gary Green 09 Oct '09

09 Oct '09

TODAY Friday 9 October 12.15 Physics PT111 Where's the Physics in Medicine? Dr Richard Watts Physics has made, and continues to make, vital contributions to modern medicine. A brief overview of the physics underlying a range of modern diagnostic imaging techniques will be presented, including X-ray and computed tomography (CT); nuclear imaging and emission computed tomography (PET and SPECT); and magnetic resonance imaging (MRI). Finally, recent advances in the use of radiation for therapy, specifically the treatment of cancer, will be shown. While much of the nuclear and atomic physics behind these techniques has been well understood for many decades, the pace of research and technical innovation continues to increase. Medicine also clearly demonstrates the importance of "blue sky" research (such as particle physics) to unforeseen but important applications. ___________________________________________ Dr Sarah Thompson Deputy Head of Department Nanophysics Research Group Department of Physics University of York YORK YO10 5DD Telephone: +44 (0)1904 432252 Fax: +44 (0)1904 432214 _______________________________________________ phys-acad mailing list phys-acad(a)lists.york.ac.uk https://lists.york.ac.uk/mailman/listinfo/phys-acad This email may be confidential and subject to legal privilege, it may not reflect the views of the University of Canterbury, and it is not guaranteed to be virus free.

YNiC seminar today
by rem 08 Oct '09

08 Oct '09

4-5 pm in YNiC Open Plan. Richard Watts, Director of MR Research at the Van der Veer Institute for Parkinson's and Brain Research in Christchurch, New Zealand and a Senior Lecturer in Physics and Astronomy at the University of Canterbury. "Diffusion MRI: Measuring the brain on microscopic and macroscopic scales" Diffusion MRI produces images that are sensitive to the random (Brownian) motion of water molecules in the brain. This motion, and hence the images that are produced, are uniquely sensitive to the microscopic, cellular environment. This has been exploited for the clinical imaging of stroke, where it can be used to both identify and differentiate between recent and old infarctions. In the the research environment, diffusion MRI produces quantitative maps that relate to properties such as cell density and myelination. In addition, measuring the directionality of diffusion (diffusion tensor imaging) in white matter allows the orientation of the fiber tract bundles to be inferred, enabling them to be traced from one part of the brain to another (diffusion tractography). This presentation will introduce that basics of diffusion MRI and its unique applications to brain connectivity, development and damage. Everyone is welcome to attend.
