We are making available an environment for linear and non-linear image reconstruction using GPU acceleration (AGILE), an open source library for GPU accelerated reconstruction problems in medical imaging.
The resource available for download includes MR reconstruction code and does not include code for fluorescence tomography or general-purpose linear algebra routines. Focusing the package on MRI reconstruction is meant to make installation easier. For the complete version of the library, reach out to us (see contact, below). There is also a MATLAB version available for download.
Conventional regridding reconstruction is shown on the left; AGILE iterative TGV on the right. Reconstructions from 48 spokes are shown on the top; from 32 spokes on the bottom. The corresponding reconstruction times on an NVIDIA GTX 480 were 8.76s (48 spokes) and 6.36s (32 spokes).
