Highly accelerated magnetic resonance imaging by under sampling and compressed sensing reconstruction: moving the burden from patient to processor

Location: CLT 7.01 Date/Time: 17th May 2016, 14:00 - 15:00
Speaker(s): Kieran Hollingsworth.

Brief Description:MRI occupies a central place in both clinical diagnosis and research, with a wide range of quantitative measurements used as end-points in clinical trials. However, MRI is underused due to long acquisition times that make it both expensive and difficult for some patients to keep still, particularly children. Conventionally, sufficient data is acquired to satisfy the Nyquist sampling condition followed by fast inverse Fourier transformation. However, MR images are compressible under transformation, such as discrete wavelet transformation, and this allows the ideas of compressed sensing to be applied to significantly under sample data (by factor of 4 or 5) and still reconstruct a high quality image. The price paid for this substantial reduction in acquisition time is that the reconstruction changes from straightforward fast Fourier transformation to an iterative minimization involving both L2 and L1 norms, imposing a much greater computational burden.

8th International Workshop on Bio-Design Automation (IWBDA)

Location: Newcastle upon Tyne, UK Date/Time: 16th August 2016 - 18th August 2016, 09:00 - 18:00

Brief Description:

The Eighth International Workshop on Bio-Design Automation (IWBDA) at Newcastle upon Tyne in the UK will bring together researchers from the synthetic biology, systems biology, and design automation communities to discuss concepts, methodologies and software tools for the computational analysis and synthesis of biological systems. IWBDA offers a forum for cross-disciplinary discussion, with the aim of seeding and fostering collaboration between the biological and the design automation research communities. This year's IWBDA will be hosted by the Interdisciplinary Computing and Complex BioSystems (ICOS) research group, Newcastle University.
