## TL;DR

RaySearch makes the vendor-neutral RayStation treatment planning system, strong in proton and adaptive planning, with machine-learning planning tools.

## Summary

RaySearch Laboratories, based in Stockholm and listed as RAY-B.ST, makes the vendor-neutral RayStation treatment planning system, strong in proton and adaptive planning, with machine-learning planning tools. Its portfolio also includes the RayCare oncology information system and RayIntelligence analytics, and RayStation is used by most proton centres. OnCo links it to radiotherapy treatment planning and QA software, proton therapy and AI auto-contouring and adaptive planning. Whether independent planning software keeps its place as machine vendors bundle their own planning and AI tools is the open question. The treatment planning technology page carries the wider picture.
