A whole-slide image is typically 100,000 pixels across at 40x, stored as a pyramid in vendor formats such as Aperio .svs; OpenSlide reads them vendor-neutrally. Slides are far too large for a neural network at once, so they are cut into tiles, encoded and pooled.","asOf":"2026-09-24","wikipedia":"https://en.wikipedia.org/wiki/Digital_pathology","links":[{"label":"Goode et al., OpenSlide: a vendor-neutral software foundation for digital pathology (J Pathol Inform 2013)","url":"https://doi.org/10.4103/2153-3539.119005"},{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Digital_pathology"}],"tags":["cansim-terms"],"related":["cancer-ai-vocabulary"],"cancers":[],"sections":[],"technologies":["whole-slide-scanners","digital-pathology-ai"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["h-and-e-staining","tile-patch-encoding","magnification"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Listed in the CanSim terms map 1.0.0 (docs/onco/terms.json, generated 2026-09-24), CC BY 4.0, attribution: CanSim project, an open, public-data-first cancer foundation-model programme; CanSim page path /terms/wsi-histopathology."],"provenance":{"editedBy":"OnCo CanSim terms wave (Wikipedia summaries, standards and project pages, GDC and FDA pages, Europe PMC)","editedOn":"2026-09-24","note":"CanSim terms map 1.0.0 (docs/onco/terms.json, generated 2026-09-24), CC BY 4.0, attribution: CanSim project, an open, public-data-first cancer foundation-model programme"},"category":"Pathology"},"route":"/terms/digital-pathology-wsi/","neighbours":{"term":[{"id":"hdf5-zarr-parquet","kind":"term","name":"Array and table formats: HDF5, Zarr, OME-Zarr, Parquet","route":"/terms/hdf5-zarr-parquet/"},{"id":"cancer-ai-vocabulary","kind":"term","name":"Cancer AI vocabulary (CanSim terms map)","route":"/terms/cancer-ai-vocabulary/"},{"id":"ehr-text-pathology-reports","kind":"term","name":"Clinical text: EHR notes and pathology reports","route":"/terms/ehr-text-pathology-reports/"},{"id":"h-and-e-staining","kind":"term","name":"H&E staining (haematoxylin and eosin)","route":"/terms/h-and-e-staining/"},{"id":"magnification","kind":"term","name":"Magnification (20x, 40x) and microns per pixel","route":"/terms/magnification/"},{"id":"tile-patch-encoding","kind":"term","name":"Tile and patch encoding of slides","route":"/terms/tile-patch-encoding/"}],"technology":[{"id":"digital-pathology-ai","kind":"technology","name":"Digital pathology & AI","route":"/technologies/digital-pathology-ai/"},{"id":"whole-slide-scanners","kind":"technology","name":"Whole-slide scanners and image management","route":"/technologies/whole-slide-scanners/"}]}}
