Exemplarily, the free software FSL-FAST (FMRIB's Segmentation Library - FMRIB's Automated Segmentation Tool) in version 4 is used for segmentation of brain tissue types. To speed up the segmentation procedure by parallel execution, we transferred FSL-FAST to a General Purpose Graphics Processing Unit (GPGPU) using Open Computing Language (OpenCL) [1]. The necessary steps for parallelization resulted in substantially different and less useful results. Therefore, the underlying methods were revised and adapted yielding computational overhead. Nevertheless, we achieved a speed-up factor of 3.59 from CPU to GPGPU execution, as well providing similar useful or even better results.}, subject = {Kernspintomografie}, language = {en} } @misc{WagnerKrenkelDoenitzetal., author = {Wagner, Thomas and Krenkel, Lars and D{\"o}nitz, Christian and Brawanski, Alexander}, title = {Influence of CFD Strategy on WSS and OSI Determination for Intracranial Aneurysm Rupture Assessment}, series = {25th Congress of the European Society of Biomechanics, July 7-10, 2019, Vienna, Austria}, journal = {25th Congress of the European Society of Biomechanics, July 7-10, 2019, Vienna, Austria}, language = {en} } @inproceedings{WeberBrawanskiPalm, author = {Weber, Joachim and Brawanski, Alexander and Palm, Christoph}, title = {Parallelization of FSL-Fast segmentation of MRI brain data}, series = {58.
