- Similarity scores, not a diagnosis
Why I built Cathra
Cancer has affected me personally. When I looked for tools like this, I found that work in this area is very limited, and there wasn’t a safe, free option anyone could explore. I saw that gap and built Cathra to fill it. I’m grateful for all the support, and hearing from people who’ve found it helpful means more to me than I can say. Thank you.

Upload an ultrasound image
Choose an existing ovarian ultrasound picture. It stays on your device and is compared to the normal and abnormal patterns.
- Use a single ovarian ultrasound view, not a collage or a screenshot of a web page.
- Higher-resolution images with fewer on-screen labels work best.

Result
These are the model's visual similarity scores — how closely the image resembles each learned pattern. They are not the probability that a person has any medical condition.
