Table 2 The comparison of properties between the endoscopic wide-field imaging and endomicroscopy
| Wide-field imaging | Endomicroscopy | |
|---|---|---|
| Resolution | Around 100 μm | 0.5–20 μm |
| Field of view | 80–140° | Ø0.3–Ø3 mm |
| Detection target | Macroscopical objects in tissue | Tissue structures in cellular and subcellular scale |
| Corresponding techniques |
Traditional white-light imaging Narrow-band imaging Linked color imaging i-scan |
Endocyto Confocal laser endomicroscopy Photoacoustic endoscopy Optical coherent tomography Coherent anti-Stokes Raman scattering Multi-photon endomicroscopy |
