Image reconstruction for 3d non-Cartesian trajectories
is still challenging due to expensive computation times.
Parallel implementations using GPUs have evolved as a
computationally effective way to tackle this problem.
Current software packages are often restricted 2d
imaging and are usually integrated in larger
reconstruction frameworks. This makes re-use challenging
especially when considering that the large majority of
code for image reconstruction is written in Matlab. This
work introduces gpuNUFFT, a new open-source 3d
regridding GPU implementation with a built in Matlab
interface that is straightforward to include in all
implementations of iterative image reconstruction.
