# Nanometer-Resolution Imaging
**Collection:** [[collections/Neurotech|Neurotech]]
**Type:** Imaging-resolution concept
**Primary source:** [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]]
## Definition
**Nanometer-resolution imaging** resolves structures at billionths-of-a-meter scale, enabling synapses, fine neurites, and cellular boundaries to be distinguished in connectomic tissue volumes.
## Relationships
- [[wiki/Electron Microscopy|Electron microscopy]] is the principal modality in the FlyWire source passage.
- The images become input to [[wiki/Machine Learning Segmentation|machine-learning segmentation]] and human [[wiki/Connectome Proofreading|connectome proofreading]].
- Resolution is one attribute; volume coverage, contrast, tissue preparation, and reconstruction accuracy remain separate.
