A fast Pytorch based GRAPPA implementation for uniformly undersampled k-space

Puntos clave

The PyTorch implementation of GRAPPA significantly reduces runtime while maintaining image quality.
Tests conducted on 8- and 32-channel MRI data exhibited similar performance to pygrappa.
The approach utilizes both CPU and GPU resources for processing efficiency.
This faster reconstruction method enhances the practical usage of MRI technology in diverse applications.

Resumen

Motivation: Existing open-source GRAPPA implementations, such as pygrappa, are slow in some cases. Goal(s): To develop a high-performance, open-source GRAPPA algorithm for faster reconstruction of uniformly undersampled data. Approach: We implemented PyTorch-based GRAPPA algorithm that can use either CPU or GPU. Results: Tests with 8- and 32-channel MRI data showed that our implementation delivers similar image quality to pygrappa but with significantly reduced runtime. Impact: This approach enables faster MRI reconstructions, making it suitable for many applications.
