Ning, K. F. et al. Deep self-learning enables fast, high-fidelity isotropic resolution restoration for volumetric fluorescence microscopy. Light: Science & Applications, 12, 1943-1960 (2023). DOI: 10.1038/s41377-023-01230-2.
One intrinsic yet critical issue that troubles the field of fluorescence microscopy ever since its introduction is the unmatched resolution in the lateral and axial directions (i.e.
resolution anisotropy)
which severely deteriorates the quality
reconstruction
and analysis of 3D volume images. By leveraging the natural anisotropy
we present a deep self-learning method termed Self-Net that significantly improves the resolution of axial images by using the lateral images from the same raw dataset as rational targets. By incorporating unsupervised learning for realistic anisotropic degradation and supervised learning for high-fidelity isotropic recovery
our method can effectively suppress the hallucination with substantially enhanced image quality compared to previously reported methods. In the experiments
we show that Self-Net can reconstruct high-fidelity isotropic 3D images from organelle to tissue levels via
raw images from various microscopy platforms
e.g.
wide-field
laser-scanning
or super-resolution microscopy. For the first time
Self-Net enables isotropic whole-brain imaging at a voxel resolution of 0.2 × 0.2 × 0.2 μm
3
which addresses the last-mile problem of data quality in single-neuron morphology visualization and reconstruction with minimal effort and cost. Overall
Self-Net is a promising approach to overcoming the inherent resolution anisotropy for all classes of 3D fluorescence microscopy.
