SOC-GRAPPA: An MPSoC based Accelerator for GRAPPA

GRAPPA is a cartesian pMRI method widely adopted for high-speed image reconstruction in many clinical applications e.g. real-time cardiac MRI. However, general-purpose computers have limited processing capabilities to address the computational complexity of GRAPPA in real-time MRI. Recently, multi-processor system-on-chip (MPSoC) has emerged as a potential candidate to meet the rising computational demands of GRAPPA for real-time image reconstruction. In this paper, design and implementation details of a novel MPSoC based GRAPPA accelerator i.e. SOC-GRAPPA are presented. The experimental results of 18-coil cardiac dataset show that the proposed accelerator is capable of reconstructing 30 frames/second in real-time cardiac MRI.
