Beyond phase signals: digital holographic microscopy and AI revealing disease-specific cell phenotypes
Bibliographic record
Abstract
Digital holographic microscopy (DHM) has emerged as a powerful quantitative phase imaging technique offering label-free, non-invasive visualization of cell structures and dynamics. Specifically, DHM provides a quantitative phase signal (QPS) that is highly sensitive, particularly to dry mass, which has led to the development of attractive applications in cell biology. QPS contains, in an intricate way, a large amount of information about the cell content and morphology. Its interferometric detection gives it a high degree of sensitivity, but at the same time it is contaminated with a coherent noise that makes a precise analysis of cell information it contains difficult. I’ll present a series of technical developments that have enabled us to obtain a quasi-coherent noise-free QPS from which we can extract a set of cellular parameters. This paves the way for high-content, label-free screening to identify disease-specific cell phenotypes. Some applications related to neuropsychiatric diseases will be presented. Finally, it will be shown how AI can take advantage of these technical developments to enable label-free cell phenotyping without the need for cumbersome instrumentation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
