Computational-Pathology

TL;DR for operators The useful part of this paper is not that it makes label-free microscopy look like H&E. That is the easy headline, and also the easiest way to misunderstand the work. The paper introduces HistoBIT3D, a dataset that pairs phase-contrast Back-illumination Interference Tomography, or BIT, with voxel-wise registered fluorescence-labelled nuclei in 3D tissue volumes.1 That matters because virtual staining has a basic governance problem: a generated image can look histological while quietly moving, deleting, or inventing cellular structure. In pathology, that is not a charming hallucination. It is the sort of thing that gets written up after the incident review. ...

Slides do not politely stay aligned. A pathology lab may scan an H&E slide for tissue architecture, an IHC slide for protein expression, a PAS slide for renal structure, and a multiplex immunofluorescence slide for cellular markers. The human story is that these images come from the same biopsy. The computational story is less sentimental: the tissue has been sliced, stained, bleached, re-stained, stretched, torn, folded, scanned, and generally treated like a fragile biological object in a world built for rectangles. ...
