Synopsis

Keywords: Synthetic MR, Data Processing, Synthetic data, Denoising

Motivation: While deep learning has advanced MRI denoising, it still relies heavily on in-vivo data, which presents challenges due to the lack of strictly noise-free ground truth and the difficulty of obtaining large, diverse in-vivo datasets.

Goal(s): We aim to synthesize complex MRI-like data from natural images to enable robust, high-quality denoising with reduced dependence on in-vivo data.

Approach: Our physics-coupled method synthesizes MRI-like data from natural images by embedding structural information into the phase, producing realistic training data without in-vivo samples.

Results: This approach achieves denoising performance comparable to in-vivo-trained models across diverse conditions, enabling effective neural network-based denoising without extensive in-vivo datasets.

Impact: Our method generates physics-coupled synthetic data from natural images, enabling effective complex MRI denoising without in-vivo data, achieving performance on par with in-vivo-trained models. This approach reduces dependence on large in-vivo datasets and addresses practical challenges in in-vivo data collection.
