Mitotic figure countingin breast H&E
Counting mitoses by hand is slow and varies between readers. Aiosyn Mitosis Breast uses artificial intelligence to detect mitotic figures across the whole-slide image before the case is opened.
Aiosyn Mitosis Breast is for research use only.
- Detection across the whole-slide image, not a sampled field
- Validated in a multi-center clinical study

Every mitosis, found before the case is opened
Drag the handle across a single H&E field. The mitotic figures a pathologist has to search for are already marked, so the work becomes faster and more reproducible.

H&E sectionDetected mitosesConsistency, and time back on every case
Mitotic counting is slow, subjective work that breast grading depends on. With Aiosyn Mitosis Breast, pathologists are faster and agree more with each other.
Less time on the slowest step
Reviewing detections replaces searching for them. Pathologists spend their time confirming a count rather than hunting across fields for the figures to count.
More consistent grading
Mitotic count is one of the most variable parts of breast grading. Detection is reproducible, so every reader starts from the same set of candidates.
The whole section, every slide
Detection runs across every field of the whole-slide image, so a long series is read the same way from the first slide to the last.
Measured with 28 pathologists
Aiosyn Mitosis Breast was validated in an independent multi-center clinical study run at Radboud university medical center, with certified pathologists reading breast biopsies and resections both with and without algorithm support.
