## TL;DR

Elekta is the Swedish radiotherapy company behind Unity, the leading MR-linac, and Gamma Knife.

## Summary

Elekta, based in Stockholm and listed as EKTA-B.ST, is the Swedish radiotherapy company behind Unity, the leading MR-linac, and Gamma Knife. Its products include the Unity MR-linac for MR-guided adaptive radiotherapy, Gamma Knife Esprit for stereotactic radiosurgery, the Harmony linac and brachytherapy systems. OnCo links it to MR-guided adaptive radiotherapy and stereotactic radiotherapy, to treatment planning and quality assurance software, to the Leeds, Sunnybrook and UMC Utrecht cancer centres, and to ideas such as coverage-with-evidence registries for MR-guided radiotherapy and an open-hardware radiotherapy machine built for unreliable power and dust. Surgery and radiotherapy curing most patients while receiving least funding is the bottleneck it bears on. Whether MR guidance improves outcomes enough to justify its cost is the open question the registries are meant to answer.
