Redrawing organ boundaries, one slice at a time
We build AI that delineates organs in CT slices — and show how far each result can be trusted.
- restore a noisy low-dose slice,
- outline each organ and colour it,
- then mark where the model hesitates.

ResearchThree questions, one pipeline
Clean the image, delineate the organs, then ask how far to trust the result — every slice passes all three.
Organ segmentation
Delineating liver, spleen, kidneys and aorta slice by slice in abdominal CT.
Low-dose reconstruction
Restoring noisy low-dose slices while keeping fine structures intact.
Uncertainty & reading support
Mapping where a model is unsure so people can review those spots first.
Slice viewerFlip through the slices yourself
Step from top to bottom, toggle each organ mask and change opacity to see where each organ appears and disappears.

DataSynthetic abdominal phantom slices v2.1 releasedMore slices, plus the annotation rules. No patient data is included. PaperOur paper on uncertainty-ranked review appears at an international workshopHow review changes when people see the slices the model is least sure about first.Looking for partners with data and questions
We welcome joint studies with hospitals and institutes, and questions about our open data. We go through ethics review and de-identification together.
