## TL;DR

Limbus AI provides AI auto-contouring for radiotherapy, FDA-cleared and used across hundreds of centres.

## Summary

Limbus AI, based in Regina, Canada, provides AI auto-contouring for radiotherapy that is FDA-cleared and used across hundreds of centres. Its Limbus Contour software segments organs at risk on CT and MR images in minutes and integrates with the major planning systems. OnCo links it to AI auto-contouring and adaptive planning. Whether automated contouring frees enough clinician time to expand radiotherapy capacity, which is the case made for it, is the open question that needs measuring. The auto-contouring technology page carries the wider picture.
