AGILE: GPU Image Reconstruction Library

AGILE: GPU Image Reconstruction Library

Author: 
Florian Knoll

AGILE (Environment for Linear and non-linear Image reconstruction using GPU Acceleration) is an open source library for GPU accelerated reconstruction problems in medical imaging. It originally included reconstruction code for both MRI (Figure 1) and Fluorescence Tomography, as well as general purpose linear algebra routines. The current version that is made available for download here only includes the MR reconstruction part to facilitate easier installation. If you are interested in the complete version of the library, just contact us. (We have also made a MATLAB version available for download.)

Figure 1: Reconstruction of undersampled radial data from 48, and 32 radial spokes (256x256 matrix). Conventional regridding reconstruction (Left column) and AGILE iterative TGV image reconstruction (right column). The corresponding reconstruction times on an NVIDIA GTX 480 were 8.76s (48 spokes) and 6.36s (32 spokes).
