Whole-slide imaging · Digital pathology

How do preclinical labs reconstruct serial whole-slide imaging into 3D volumes?

Serial sectioning and whole-slide imaging produce a stack of two-dimensional pathology slides. Three-dimensional reconstruction reveals structure that slide-by-slide review cannot: continuous vessel courses, immune microenvironments, and patterns of tumor infiltration across the specimen. You need a registered 3D volume to quantify those structures and to correlate histology with micro-CT or light-sheet from the same specimen.

What researchers typically do

Most digital pathology workflows stop at 2D: pathologists and researchers review individual whole-slide images in QuPath, Indica Labs HALO, Leica Aperio, or open-source viewers. That works for focal lesion review and stain scoring on a single plane. Reconstructing serial sections into 3D is often a separate custom pipeline: manual alignment of adjacent sections, interpolation between sparse levels, or research-only tools that do not connect to anatomic imaging from the same study. Multi-stain registration (H&E followed by IHC, for example) adds another alignment step per specimen. Labs pursue 3D reconstruction despite that friction because two-dimensional review misses continuous structure: how vessels course through tissue, how immune cells organize in three dimensions, and how tumors infiltrate across serial levels. Those questions require a registered volume, not isolated slides.

Serial whole-slide reconstruction in sample space

With the NeuroSimplicity Digital Pathology Module, you can reconstruct serial whole-slide imaging into three-dimensional volumes in native sample space, registering sections across the stack and aligning multi-stain series through deterministic, auditable pipelines on institutional infrastructure. You can trace continuous vessel courses, map immune microenvironments in three dimensions, and quantify tumor infiltration across serial levels, then compare those regional metrics across treatment and control groups without reviewing slides one at a time. When you license the Anatomic Imaging and Molecular Imaging Modules together, you can register reconstructed histology to in situ micro-CT and light-sheet from the same specimen for correlative analysis in native sample space.

What the platform enables

  • Serial whole-slide imaging (WSI) reconstruction into 3D sample-space volumes
  • 3D visualization of vessel courses, immune microenvironments, and tumor infiltration across sections
  • Multi-stain serial section registration (H&E, IHC, and other stains)
  • Quantitative regional analysis and cohort comparison in native sample space
  • Cross-modal integration when the full Imaging Suite is licensed

More detail

The Digital Pathology Module is one of the modules you select when licensing the Imaging Suite. The first module is included in the base platform license; each additional module is an add-on.

Spatial omics datasets collected on serial slides share similar reconstruction challenges. See the spatial omics guide linked in Next steps.

To register reconstructed histology volumes to micro-CT, light-sheet, or spatial omics from the same specimen, see the multi-modal integration guide linked in Next steps.
