IMPATIENT MRI Toolset

The IMPATIENT MRI toolset is an implementation in CUDA for iterative MR image reconstruction using Graphics Processing Units (GPUs). It is used in the research of medical imaging, especially in the area of image reconstruction for magnetic resonance imaging (MRI). In our experiments, this implementation significantly reduces the computation times by two orders of magnitude (compared with the non-GPU implementation) while accurately compensating for field inhomogeneity.

News: IMPATIENT MRI toolset version 3.1 alpha is released.
