Richard Ansorge

Richard Ansorge with PET-MR magnetI am currently working on a new book On GPU accelerated Scientific Computing CUDA in Context

My research interests include Medical Imaging, particularly PET and MRI. Much of this work has been 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 completed is the construction of a combined PET and MRI scanner. This system allows simultaneous imaging with both modalities.  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

Here is a plug for my recent book The Physics and Mathematics of MRI

Here is a link to my first computer program written in 1964 (in EDSAC 2 Autocode)

This work was done as part a Digital Computing class given by Maurice Wilkes in the Lent term of my first year reading mathematics with physics.
