GPU Accelerated Compressive Sensing in MRI

We introduce a new approach to get faster MRI acquisition. By reducing the number of data-samples in combination with a new MRI reconstruction method, we are able to reduce the acquisition time by a factor 20 without introducing disturbing artifacts. …

Quasar tutorial: High-level programming of Heterogeneous Hardware

The use of graphical processing units (GPUs) for general purpose calculations has gained a lot of attention, since speed-up factors of 10x-50x compared to single-threaded CPU execution are not uncommon. This makes the use of GPUs for scientific …
