Fiber-scanned CWDT delivers qualitative 3D volumes from cleared poplar and mycelium using $50 hardware stack
Ingold et al. show that scanned white-light fiber illumination plus inexpensive positioning yields usable 3D reconstructions of biological samples. Evidence rests on exploratory qualitative volumes from four specimen types without quantitative validation metrics. The work suggests a pathway to sub-$100 internal imaging but requires controlled resolution and repeatability studies before clinical translation.
Next steps include side-by-side comparison against micro-CT on the same fungal-root specimens and open-sourcing the reconstruction code to test reproducibility across labs. If resolution reaches 50 microns on phantoms within a year, the method could support rapid materials inspection or cleared-tissue histology in low-resource settings.
Ingold: Benchtop CWDT prototypes will demonstrate 50-micron isotropic resolution on standardized scattering phantoms at a 2027 microscopy conference.
