Abstract
Disclosed herein are systems, methods, and instrumentalities associated with MRI image reconstruction. According to embodiments of the disclosure, an apparatus configured to perform the MRI image reconstruction task may be configured to obtain an under-sampled MRI image and generate a reconstructed MRI image based on the under-sampled MRI image and a machine-learned (ML) model. The ML model may be trained via contrastive learning, during which randomly selected locations of the reconstructed MRI data generated by the ML model may be replaced with values that are different than the under-sampled MRI data, and the MRI data thus derived may be used as a negative example for the training.
