Richard Ansorge

Richard Ansorge with PET-MR magnetMy current research interests involve Medical Imaging, particularly PET and MRI. Much of this work is done as a collaboration between the Physics Department and the Clinical School, especially the Wolfson Brain Imaging Centre.

Martin Graves and I have recently finished a book on the Physics and Mathematics of MRI. The book is suitable for readers with backgrounds in physical sciences, engineering or computing.


One major project I have recently completed is the construction of a combined PET and MRI scanner. This system allows simultaneous imaging with both modalities. A this poster gives further information.

I am interested in using GPUs for fast medical image processing. Together with Audrunas Gruslys we have developed Ezys which performs fast and accurate affine and elastic 3D registration on typical MR image data. Currently Ezys uses NVIDIA GPUs and CUDA. Minimum GPU requirements are compute 2.0 and ~1.5 GB of video ram.

An older example also using CUDA is here AIRWC - Accelerated Image Registration with CUDA
