    Optical diffusion tomography can now image complex objects like airplane models in tissue phantoms. This advancement uses a backpropagation algorithm and a single planar view for 3D localization, moving beyond simple spherical targets.

    Area of Science:

    • Biomedical optics
    • Medical imaging
    • Photonics

    Background:

    • Optical diffusion tomography (ODT) is an emerging imaging modality.
    • Current ODT demonstrations primarily image simple spherical objects.
    • Imaging complex, resolved objects in turbid media remains a challenge.

    Purpose of the Study:

    • To reconstruct images of resolved objects (airplane models) in tissue phantoms using ODT.
    • To demonstrate 3D localization of resolved objects using a single planar view.
    • To adapt ODT for imaging non-spherical targets in scattering media.

    Main Methods:

    • Utilized a backpropagation algorithm for image reconstruction.
    • Employed a planar geometry for data acquisition.
    • Generated diffuse photon density waves using kilohertz modulation (near-DC illumination).

    Whole-cell Super-Resolution Imaging via DNA-PAINT on a Spinning Disk Confocal with Optical Photon Reassignment

    Published on: January 6, 2026

    Main Results:

    • Successfully reconstructed images of resolved airplane models embedded in tissue phantoms.
    • Demonstrated the ability to locate these resolved objects in three dimensions.
    • Achieved 3D localization using only a single planar view, overcoming limitations of spherical targets.

    Conclusions:

    • ODT can image and localize complex, resolved objects in turbid media.
    • A single planar view is sufficient for 3D localization with this backpropagation method.
    • This technique expands the potential applications of optical diffusion tomography in biomedical imaging.
