SNRAware is an imaging transformer model trained to denoise complex MR image data. Imaging transformers use attention modules to capture local, global, and inter-frame signal and noise characteristics. Denoising training used the SNRAware method, generating MR-realistic noises on the fly to create low SNR samples with unitary noise scaling. Model received low SNR complex images and g-factor maps as input, producing high SNR complex images as output. It is provided as research-only model for reproducibility of the corresponding research.
