Self-supervised signal denoising in magnetic particle imaging

Main Article Content


Various noises restrict magnetic particle imaging (MPI) to achieve higher resolution and sensitivity in practice. In this study,we proposed a self-supervised learning method to denoise MPI signals. The deep learning-based architecture consisted with four
encoder’s blocks (EcBs) and four decoder’s blocks (DcBs). This model was trained with limited data of MPI magnetization signals to efficiently suppress noise related features by directly learning from the noisy signals. Simulated experiments showed that the selfsupervised method could reduce the noise interference in MPI signals and eventually improve image quality
